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?

Problems with the arteries and veins present in the hands or legs can lead to vascular disorders. The arteries carry blood from the heart to other parts of the body in order to deliver nutrients and oxygen. The veins carry the blood back to the heart, after the nutrients have been used up. If these blood vessels of the arteries or veins become blocked or narrowed, it can lead to a vascular blockage.

A vascular blockage that occurs in the hands or legs comes under the category of Peripheral Artery Disease or PAD. These type of disorders are less common in the upper extremities of the arms or hands than in the lower extremities of legs. Few of the signs for the same are:

Pain and difficulty in movement due to decreased blood flow
Numbness or weakness of leg or fingertips
Sores on the toes or feet
If the blockage is deep, symptoms of redness, swelling, extreme pain or cramping can be experienced
Abnormal color changes in the fingertips
Ulcers or wounds that don t heal
Skin sensitivity problems when in cold temperatures
How can it be diagnosed?
The blockage can be detected by various methods namely-

Physical Examination   Your doctor may find decreased pulse at armpit, wrist or fingers, full veins, masses, wounds or gangrene.
Doppler or Ultrasound examination to determine the blood flow in the arteries and veins
MRI Scan of the affected area to pay special attention to the blood vessels
Cold Stress Test
Arteriography to show clear blood vessel details
Angiography to map blockages and narrowing of the arteries
What are the Risk Factors for Peripheral Artery Disease?
An individual is at risk for developing vascular blockages in the hands or legs if one or more of the following factors are present:

Smoking
Diabetes
Heredity Factors   A personal or family history of blood vessel disease
High blood pressure
High cholesterol
Aging   People aged above 50 years and older are more prone to vascular blockage
Can it be treated?
Treatments for vascular blockage can vary depending on the age, cause of the blockage, intensity and overall well-being.

Treatments can include:

Self-care   Reducing risk factors and making lifestyle changes to quit smoking, sedentary life or diabetes, blood pressure and cholesterol management can reverse symptoms of vascular disease.
Medications   A variety of drugs can be prescribed to lower the risk and progression of narrowing blood vessels or prevent blood clotting.
Interventional Procedures   Minimally invasive surgery like saloon angioplasty, stenting or removal of artery plaque build-up.
Surgery   If the blockage is severe, surgery may be performed to lessen the vessel narrowing, reconstruct the artery or tie it off, depending on the circumstances.

Pain in the Hands or Legs!

Hot and Cold therapy is one of the most popular home remedies for any kind of joint pain or muscle sprain. In some cases applying heat therapy and cold therapy alternatively, can help relieve the pain while for others only one form of therapy is necessary. To understand what to use when, one should first understand the effect of heat and cooling on the body.

Applying a heat pack or immersing the affected limb in hot water improves blood circulation and makes the muscles more flexible. Thus, it can help relax a muscle and fasten the healing of damaged tissues. On the other hand, cold therapy or cryotherapy reduces blood flow to the affected site. This helps relieve inflammation and pain caused by it. It can also make the area feel numb by reducing nerve activity temporarily.

Types of Heat Therapy
Heat therapy can be categorized as dry heat and moist heat. Dry heat involves using saunas or dry heating packs to relieve pain. This is also known as conducted heat therapy. As the name suggests, moist heat involves the use of steamed towels, hot baths and moist heating packs. This is also known as convection heat therapy. Moist heat is usually considered more effective than dry heat.

Types of Cold Therapy
Cold therapy may be applied to a part of the body or to the entire body. This includes ice packs, coolant sprays, ice baths, ice massages and whole body, cold therapy chambers.

How to use heat and cold therapy?
The sooner heat and cold therapy is given to a person, the faster they will recover from their pains. Heat therapy can be given to a person for extended periods of time but when giving cold therapy, a person should not be exposed to a cold pack or ice bath for more than 10-15 minutes. Care should also be taken no to apply ice or a frozen pack directly on the skin as it can damage the skin and nerves.

When not to use Heat Therapy?
If the injury site is swollen or bruised, cold therapy is better than heat therapy. Heat therapy should also not be applied to an open wound. People suffering from conditions such as diabetes, dermatitis, deep vein thrombosis, vascular diseases and multiple sclerosis should also avoid heat therapy as these conditions can increase the risk of burns and other such complications. Pregnant women should also consult a doctor before using a hot tub or sauna.

When not to use Cold Therapy?
Cold therapy is avoidable for treating stiff joints and muscles. People suffering from poor circulation and sensory disorders should also avoid using cold therapy without a doctor s supervision. 

Hot & Cold Therapy - How It Can Treat Pain?

Excessive and persistent pain in the feet as well as the ankle joints could point at the existence of a condition known as flat foot pain. This happens due to the difference between a normal foot and a flat foot. While a normal foot will have an upward arch under the foot, right in the middle, the flat foot does not have such a support. This arch is usually formed by the tendons and ligaments that help in rendering support to the foot as well as stabilising the rest of the body. When these tendons and ligaments become weak, the arch begins to diminish before finally disappearing, which leaves the patient with a flat foot. This can be a painful condition. Let us look at the ways in which it may be cured.

Foot Wear: When you are suffering from this condition, it is important to wear comfortable and supportive foot wear like shoes, sandals and slippers which can support the arch and help in giving stability to the rest of the body. Besides looking for shoes that will provide the right amount of comfort, one can also use additional support like insoles that will help in giving comfort while you are walking, standing or running.
Orthotics: These are tools that can be recommended by your doctor in order to help in minimising the pressure that one feels in the foot. The orthotics usually distributes this pressure by giving much needed additional support to the arch of the foot. These tools also help in realigning the foot s ankle with its bones as well as the joints, which can help in successfully treating this condition to a great extent. They are usually customised as per your exact foot shape and size, as well as the problem you are facing, so that you have plenty of support when you are using your feet for varied activities.
Arch inserts and wraps: If your normal shoes are lacking the arch support that you require for flat feet, then you can also invest in arch inserts and wraps which will reduce the pain and prevent it from reoccurring. Also, these will help you to remain standing or walking for longer periods of time, as they add that extra bit of support to your feet for normal functioning.
Surgery: If the various non surgical treatments do not help you over a period of a few months, then it may be time to speak with your podiatrist or orthopaedic specialist so that you can go in for a surgery that will fix this problem. This kind of surgery will help in stabilising the feet and ankle bones by applying corrective foot support.

Flat Foot Pain - Ways It Can Be Treated!

A menstrual cramp is something which every woman complains of for a day or two every month. Menstrual cramps are usually the pains felt in the lower abdomen, which can occur both before and during a woman's menstrual period. These cramps are caused by a hormone called prostaglandin that causes the uterine muscles to contract during menstruation. When the uterus contracts to shed its natural lining during your period it releases a hormone called prostaglandins which causes pain and inflammation. So higher the level of prostaglandins more severe the menstrual cramps.

It might be just a minor discomfort for some, but for others it can be severe. The symptoms of menstrual cramps include pain in the abdomen, pressure in the abdomen and pain in the hips, lower back, and inner thighs as well. However, if the cramps are severe you might have an upset stomach, loose stools and vomiting too.

Three out of four women experience menstrual pains and every one out of 10 women experiences severe cramps. Here are few remedies that might help in relieving the pain:

Exercise, brisk walking or any type of physical activity can help to ease your belly pain as by being physically active your body pumps more blood, which helps in releasing endorphins to counteract the prostaglandins and reduce your cramps.
Apply heat on the lower abdomen or the area where you feel the pain as it helps to relax the contracting muscles in your uterus.
Improve your diet by reducing fat and increasing vegetables. However, avoid foods that contain caffeine and salt.
Take a warm bath as it may also provide some relief.
Add ginger in your food as it helps in lowering the levels of the pain-causing prostaglandins.
Drink chamomile tea at least three times a day.
Take fish oil supplements, vitamin B1 or both.
Make sure to get enough vitamin D.
Have an orgasm as it releases endorphins which has a pain-relieving effect and helps in boosting your mood as well.
Include more dietary magnesium such as dry almonds and boiled spinach as it helps to ease the pain of cramps.
Acupuncture also has an anti-inflammatory effect.
Take a safe painkiller to reduce pain.
Birth control pills may help relieve painful cramps, but they do come with side effects which may include spotting, breast tenderness, nausea and low sex drive.
Refrain yourself from smoking and drinking alcohol.
Finally, have appropriate rest.
Note: If you still do not get any relief despite trying some of these options then you must visit your doctor to rule out more serious health issues as the menstrual cramps are sometimes caused or worsened by other conditions and any sort of medications for such cramps are to be taken after consulting a Gynaecologist.
