Why does PAIN occur? Understand the Mechanism of Pain

Pain is an unpleasant and distressing physical sensation caused by disease or injury, which induces hurt and anxiety in those suffering from it.
There are many different manifestations of pain, ranging from short term (acute pain) to long term (chronic pain). Other classifications include pain in the internal organs (visceral pain), injured tissue (inflammatory pain), nerves (neuropathic pain), etc.

The reason for the occurrence of pain depends on the cause and kind of pain being experienced. In most cases, pain acts as a warning sign that the body has been afflicted by a disorder of some sort, which may have arisen due to internal sickness or external wounding. Acute pains are generally cured on their own through rest or simple medication. Chronic pains, on the other hand, are more complicated in nature and the treatment requires more elaborate diagnosis.

The mechanism of pain

Pain is an extremely personal and subjective experience and affects each individual to varying degrees. The pain signals, which can arise in any part of the body, travel through the spinal cord to the brain along thousands of specialized nerves and nerve fibres. In the brain, it is processed in the centres associated with anxiety, emotions, memory, appetite, etc. Signals and pain inputs are then returned from the brain to the spinal cord, which may heighten or diminish pain.

In some cases, pain may also be induced by damage to the brain and spinal cord, which happens after a stroke.
A constant barrage of pain signals may cause the cells at the end of nerve fibres to become over-sensitized. This is known as 'wind-up' and is one of the most common causes of chronic pain that occurs even though the root of the problem has been identified and treated.

The causes and effects of pain differ from case to case depending on the signals received by the brain and its interpretation. It affects the individual's day to day activities and if persistent, can also have a harmful impact on mental health and psychosis. Pain is always handled, diagnosed and treated differently in all patients by drawing out the best possible solution to the problem.





Why does PAIN occur? Understand the Mechanism of Pain

If you suffer from chronic pain of any kind, it is important for you to know that it is associated and linked with your emotions. Other than your physical activities and personal relationships getting hampered, unwanted feelings like resentment, stress and frustration are also common. These emotions and feelings are capable of making your chronic pain condition more worse. 

The Relationship between your mind and body: Your mind and body work together and cannot be separated. Your mind controls all your thoughts and also affects the way in which pain is controlled or perceived by the body. Pain and the fear of pain may lead you to avoid activities. This may reduce your physical strength and cause disruption in the functioning of your body.

Stress: Stress affects your body both physically and emotionally. It may lead to an increase in your blood pressure, breathing rate, heart rate and muscle tension may also occur. These may lead to fatigue, appetite changes and sleep disruption. Stress also causes depression, anxiety, make you dependent on drugs and make you dependent on other people.

Depression: Depression is common among chronic pain patients. Chronic pain can make cases of existing depression much more worse and the existing pain is also worsened. There are chances of developing depression from chronic pain if depression runs in your family or genes. 

Symptoms of Depression are as follows:

Feeling sad, angry, worthless and hopeless frequently
Lack of energy
Lack of interest in regular activities
Difficulty in sleeping
An increase or decrease in appetite, which may lead to major weight gain or weight loss
Difficulty with concentration
Having suicidal thoughts and thoughts about dying or harming oneself
How to Handle your Emotions during Chronic Pain: A common therapy, which people with chronic pain undertake is called Cognitive Behavioural therapy. You should seek the help of a therapist. In this therapy, you will learn about thinking in a positive way instead of drowning in negative thoughts. Your fear of pain will be reduced and you will learn how to strengthen important relationships. You will be able to develop a sense of freedom from chronic pain. 

If your chronic pain occurs due to an accident or emotional trauma, you may be assessed for post-traumatic stress disorder (PTSD) by your healthcare provider. Many patients suffering from PTSD cannot deal with their pain until the emotional stress is dealt with. If you feel depressed and cannot control your emotions, you need to consult a doctor.

Chronic Pain - Is it Linked to Our Emotions?

Dysmenorrhea is a condition marked by severe menstrual cramps. This is caused due to contractions in the pelvic area during the menstrual cycle. While most women go through some degree of cramping, when the cramps become too serious and severe, it should be reported to a doctor to find out if there are any other related problems like Endometriosis, Fibroids, Adenomyosis or some infections.

Here are the ways in which this condition may be treated effectively:

Medication: One of the main ways of dealing with this condition includes taking pain relievers that must be prescribed by your doctor. Also, one can take over the counter drugs to relieve the pain. These include ibuprofen as well as aspirin and non-steroidal anti-inflammatory drugs. Acetaminophen can also help in most cases. Some women may need antibiotics to take care of pelvic infections that cause pain in the pelvic region.

Hormonal Birth Control: if your symptoms are too severe and debilitating, then the doctor can also put you on hormonal birth control treatment to bring down the pain and severity of the cramps. These are usually prescribed in the form of oral tablets which need to be consumed daily as advised by the Gynaecologist . Sometimes, some women may be unsuitable / unwilling for oral medications and in such cases, other routes for hormonal administration may be followed. This can be administered in the form of an injection. Also, you may wear the dose as a patch on the skin. A surgical procedure can also implant the same under your skin. This also comes as a flexible ring that the doctor can insert into your vagina with the help of an intrauterine device (IUD).

Surgery: In very extreme cases, the doctor may recommend surgery. This is usually conducted in case there is an underlying condition like endometriosis or fibroids, which can create severe complications for the patient as well. The doctor may also carry out surgical removal of the patient's uterus in case there are many complications.

Home remedies: One can exercise on a regular basis in a moderate manner so as to ensure that the cramps are not too severe. Also, you can use heat therapy in order to bring down the pain. This can be done by taking a hot bath and soaking in a tub of hot water. Also, you can use a heat compress so as to relieve the pain. Other dietary supplements can also be taken in order to reduce the cramps. For this purpose, one should regularly indulge in fish and flax seeds as well as other ingredients that are rich in omega three fatty acids. Also, vitamin B1 is an important ingredient that can be found in leafy green vegetables. Magnesium supplements can also be taken by the patient for such cramps.

Stress: one will need to take care of the stress levels by staying away from stressful situations and also cutting back on the consumption of alcohol. One should also avoid smoking completely. Meditation & Yoga have been known to help in relieving stress and you can practise a little bit of these on a daily basis. Also, devoting time to your hobbies and listening to good music can be a stress-buster when incorporated in your daily routine.

So eat right, exercise right, think right and have a positive attitude- That helps take care of most non-pathological cases of dysmenorrhoea.

Ways to Treat Dysmenorrhea Effectively

Avascular Necrosis, also termed as Ischemic Bone Necrosis or Osteonecrosis is a medical condition characterized by the bone death on being deprived of blood. The condition is known to occur in the shoulder, ankles, and knees. However, the part of the body most affected by Avascular Necrosis is the hip. In this article, we will describe the conditions that contribute towards Avascular Necrosis of the hip along with the associated symptoms.

Factors that lead to Avascular Necrosis of the hip
The supply of blood to the bones may be interrupted by a myriad of factors some of which include

1. Certain medical conditions and health disorders such as

Gaucher's disease: A genetic disorder resulting from glucocerebrosidase enzyme deficiency. As a result, glucocerebroside gets deposited in the cells of the macrophage-monocyte system.
Sickle cell anemia: A genetic disorder which results in the RBC's appearing like a sickle cell instead of being round shaped.
Both of these conditions bring about a significant reduction in the supply of blood to the bones resulting in Avascular Necrosis.

Certain inflammatory conditions that may damage the arteries and trigger Avascular Necrosis of the hip include autoimmune diseases, pancreatitis or HIV infection.

2. Extensive and prolonged use of corticosteroids: Often used as non-inflammatory drugs, corticosteroids can play a contributing role, resulting in Avascular Necrosis (non-traumatic). The fatty substances are usually broken down by the body. However, the use of corticosteroids may affect this breakdown as a result of which the fatty substances start piling up in the blood vessels, constricting their size. The constricted blood vessels, in turn, reduces the supply of blood to the bones to a great extent.

3. An injury or a fracture affecting the femur: A hip fracture or a dislocation that affects the upper half of the thigh bone or the femur acts as a potential threat, triggering a traumatic Avascular Necrosis (AVN) of the hip.

In some case, radiation therapy or chemotherapy for cancer can go a long way in interfering with the ability of the bone (weakens the bone) to receive blood, causing bone death.

People who are into heavy drinking stand a greater risk of suffering from AVN. An increased consumption of alcohol causing constriction and narrowing of the blood vessels interfering with the flow of blood to the bones.

Symptoms characteristic of AVN of the hip

Unfortunately, the initial stages of AVN are asymptomatic. However, as the condition progresses into later stages, a person may experience pain and discomfort, particularly while exerting pressure on the bone affected by the condition.
As the bone and the adjacent joints deteriorate and collapse further, a person may experience great difficulty in using the joint altogether.
In some cases, the condition may progress and affect both the hips (Avascular Necrosis Bilateral).

Causes and Symptoms of Avascular Necrosis of the Hip

Vaginismus is a condition characterized by significant pain in the vagina generally during sexual intercourse. This pain occurs on penetration due to the contraction of the vaginal muscles.

Causes

The exact cause of Vaginismus is not exactly known to the doctors. But some researchers suggests that the pain might result from severe anxiety or illogical fears before sex.

Vaginismus can be primary or secondary depending on the concerned woman s previous sexual experiences. Vaginismus can be linked to an earlier sexually painful experience, sexual trauma or psychological factors. In some cases, the pain tends to exist without any direct physical cause. The causes of the pain might vary from women to women and might occur in some cases with only one specific partner and not with others.

Sometimes the pain might stem from underlying infections or any other underlying complications.

The symptoms of Vaginismus are as follows:

Severe pain during intercourse.

Severe pain during insertion of tampons or during any medical check-ups.

The following treatments can be useful to treat Vaginismus:

If the pain arises due to anxiety or fear, counselling sessions can help you to a remedy.

If the pain arises whenever something penetrates the vaginal walls, progressive desensitization can be useful to treat the pain. The process aims to loosen the vaginal muscles so that you don t experience any pain during sexual intercourse.

Kegel exercises (at least 20 of them) can help in the initial stage to relax the vaginal muscles. After you exercise for a few days, you should try inserting one finger inside your vagina while doing the exercises. Try doing it gently and if it still hurts, try doing it with a lubricating jelly. This continuous procedure will help in the contraction of the vaginal muscles which eventually relax.

Vaginismus - Things You Should Be Aware of 

Acupuncture is a kind of therapy that combines needles with pressure and pain points in order to delicately apply pressure for pain relief. This form of physical therapy is being increasingly recognised as an efficient method of treating pain in joints, muscles, bones and even for migraine pain. So let us find out more about Acupuncture and pain management.

    Chronic or Long Term Pain: There are many ailments that cause chronic or long term pain. These include back pain, neck pain, stiffness in the joints, osteoarthritis, headache and migraine, and pain in the shoulders. All this can be treated over a long period of time with the help of simulated acupuncture which uses pointed apparatus for activating better blood circulation for overall improvement in the pain that is being experienced in the area. The use of this apparatus helps in avoiding the harmful medication that can have adverse side effects.
    Menstrual Cramps: A fine needle method at the right points can help in bringing down the symptoms of the painful condition called dysmenorrhoea during menstrual cycles. With acupuncture, the acupuncturist can administer acupoint therapy to relieve menstrual cramps. This will help in moving the qi, or life force, in a better way so that the pain will stop. 
    Acute Pain: Over use of muscles, joints and repetitive, work related movements and strain can lead to acute pain. This includes wrist pain, shoulder pain, elbow pain, back pain, lower back pain, neck pain and even leg pain. With acupuncture, the patient gets rid of the pain in close to twelve sittings.
    Pain due to Cancer Treatment: Cancer and its treatment can take a heavy toll on the body and lead to a series of complications which also includes pain. A clean needle procedure can be followed along with the chemotherapy and radiation or after it, so as to relieve the patient of the pain experienced. Also, it can be used to replace traditional chemotherapy and radiation. 
    Better Rest: When the needles or apparatus touch the pressure points and circulate the blood and life force, it actually creates a soothing effect and helps the patient sleep and get better rest. This is also a requirement for pain relief. It can bring better blood flow to the area and help in removing anxiety and stress related to pain so that there is better chance of getting rest. 

With the use of acupuncture, pain can be taken care of with the needles and various tools that come in various shapes. These tools and equipment can also use laser treatment along with the point focused treatment.
