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.

In case your lower back pain is not under control and you have been neglecting it, you are susceptible to acute pain, sciatica, nerve pain and pain in other regions caused from a pinched nerve. Long-term pain in the back portion can lead to permanent ailments like degenerative disc disease or spinal stenosis.

Probable causes of lower back pain
Severe pain in the lower back region can be caused due to a herniated disc, back muscle pain, ligament strain or any other non-specific pain. An individual may also suffer from lower back pain due to systemic conditions like rheumatoid arthritis, fibromyalgia or ankylosing spondylitis.

Stages for assessing and treating lower back pain
Managing the back pain is the primary objective of physiotherapy. In reality, back pain is the final symptom that is developed and the first thing that must be addressed.

Stage I
Back pain relief: The physiotherapist is going to use different types of tools and items to help the pain subside along with the inflammation. These include electrotherapy, acupuncture, ice application, soft-tissue massage and deloading taping techniques. Sometimes the physiotherapist may also recommend an anti-inflammatory drug if the pain is intolerable.

Stage II
Restoring normal strength: With the settling of pain and inflammation, you are more susceptible to injury because though your pain has subsided, your ligaments and muscles are weak. Your doctor will aim at restoring normal motion of lumbar spine, muscle endurance and strength, proprioception, balance and walking abilities.

Stage III
Restoring full body function: Depending on your daily chores and activity, your physiotherapist will aim at restoring the function of your back portion to keep you safe while performing the chosen activities.

Osteoporosis is a disease that affects the bones of its sufferers. This is most commonly found in women, especially in those who are close to, or going through, menopause. Hormonal changes around this period in a woman's life usually lead to various changes in her body. One of these changes includes loss of bone tissue which can leave the patient with brittle and weak bones, a condition that is also known as osteoporosis. This condition literally imbibes the word porous, meaning hollow bones. It is born from an acute deficiency of calcium and vitamin d. The dexa scan or bone density test, also known as the dual energy x ray absorptiometry scan, is one of the most effective tests that can help you in detecting this kind of damage or thinning bones. Here's why.

- fractures: the dexa scan is an important one because it sends low energy beams to areas like your joints and tissues to show how susceptible you are to fractures. It does so by measuring the strength of the tissues as well as the bones to see how brittle they may be.&nbsp;

- other ailments: measuring the thinning of your bones can also point to the presence of other ailments that may have gone unnoticed or undetected, earlier. These can include kidney disease, hyperparathyroidism which happens due to overactive secretions of the said gland, as well as liver disease due a malfunctioning liver, intestinal disease and various disorders in the intestinal tract, and a serious vitamin d deficiency. With this scan, you can get an insight into the other parts of the body affected by the bone density, and whether or not they are functioning properly.&nbsp;

- estrogen: simply checking the estrogen levels cannot ascertain whether or not you have osteoporosis, as a high estrogen level can be credited to a particularly heavy period cycle. It does not show the bone health the way a dexa scan does.&nbsp;

- easy and standardised: this method of scanning usually happens with the help of a mounted x ray machine type, hand held gadget which can be extended to conduct the scan. This is an easy and standardised method that releases low levels of radiation which also makes it a healthier option.

- bone density scores: the t scores and z scores point towards the bone density and help in diagnosing the condition efficiently. With a systematic scoring system, it is a sure shot test for osteoporosis.

Osteoporosis is a serious condition. The first step in treating the same is to get a detailed scan like the dexa scan done, so as to test the extent of the bone thinning to ensure that proper and timely treatment takes place.&nbsp;


Why Is The DEXA Scan Important For Osteoporosis Patients

Arthritis is a very painful disease. It restricts you from doing a lot of the activities you would love to engage in. However, there are steps you could take to reduce the chances of it happening to you. Here are some tips, which help you in preventing Arthritis:

2. Take Vitamins and olive oil
Vitamins are crucial, especially A, C and D. Vitamin A can be found in carrots. vitamin D can yet again be found in fish while vitamin C can be found in strawberries, mangoes, pineapples and oranges. Olive oil is also useful because it contains polyphenols which reduce the chances of developing arthritis.

3. Eat ginger and broccoli
Ginger and broccoli are two of the most therapeutic foods for various reasons and the chances of getting arthritis are also proven to reduce due to these foods.

4. Avoid injury
Although this is very hard to do sometimes, avoiding injuries do reduce your chances of getting arthritis.

5. Control your weight
This is very important, especially for your knees. It has been proven by researchers at John Hopkins University that if you are 10 kg overweight, then 30 to 60 extra kilograms of weight fall on your knees.

6. Exercise
Strengthening your muscles around your joint decreases the pressure on the joint. If there is less pressure on the joint, then the chances of arthritis are reduced. The best way to decrease pressure on the joint and strengthen your muscles is to exercise.

6 Tips To Prevent Arthritis

The bones are a porous matrix which is filled with minerals like calcium and phosphorus which make them strong. Over a period of time, the mineral content is lost and therefore the matrix gets brittle. Bones are more likely to fracture in these people.

Causes/Risk factors:

The bones get fragile and brittle with age in most people, and people over 60 years of age are likely to be affected
Asian women about the age of 45 are prone to osteoporosis
Reduced vitamin D intake (either by sun exposure or through diet) also makes bone porous and prone to fracture
Sedentary lifestyle with minimal or no exercise
Lower levels of estrogen, especially post menopause
Cigarette smoking
Reduced testosterone levels
With fracture, there is severe pain, loss of mobility, and need for prolonged nursing.
Foods which can help control/prevent osteoporosis:

Yoghurt: Derived from milk, it is rich in animal protein and also contains good amounts of vitamin D and B2, calcium, phosphorus, and magnesium. It helps in maintaining estrogen levels during menopause, thereby preventing osteoporosis. They also provide a good supply of gut bacteria, which improves immunity.
Milk: Similar to yoghurt, this is also rich in various minerals that are essential for bone health. The vitamin D in it also improves calcium absorption, thereby prolonging the occurrence of osteoporosis.
Fish and meat: Lean meat and fish are good sources of oils and protein and form an essential part of diet for preventing osteoporosis. Sardines and salmon are ideal as the tiny fish are rich sources of calcium.
Eggs: This contains good amounts of natural protein, minerals, and vitamins essential for bone health. It also helps in estrogen formation, which has a bone-protective effect.
Cabbage: Any form of cabbage is good for preventing osteoporosis. It promotes bone metabolism and has calcium which help in strong bone formation.
Bananas: Another effective food in preventing osteoporosis, it helps improve absorption of calcium and other essential nutrients to ensure bones are formed and maintain health. It also has natural oils, potassium, and vitamins A and C in good quantity.
Almonds: It forms an integral part of preventing osteoporosis by increasing bone density and promoting bone health. It also has good oil content, which is also essential for bone health.
Legumes: Beans and other legumes are rich source of proteins and minerals and therefore prevent onset of osteoporosis.
Chickpeas: Another great source of various minerals and vitamins, it is very low in calories and sugar and is great to lose weight. It also improves bone health by increasing density.

Osteoporosis - How A Healthy Diet Can Reduce Its Risk?

Gridhrasi is what Sciatica is known as in Ayurveda. It is the disorder that causes mild to agonizing pain in the sciatic nerve or neuralgia. These nerves, emerging from the pelvis, run along the hamstring and may cause intense pain in one or both the legs when a person suffers from Sciatica. Sciatic pains fill your life with misery as the simplest of daily activities cause sudden and excruciating pain. There are two types of sciatica i.e. true sciatica and pseudo sciatica. Sciatica may be caused due to bulging disc or herniated disc, degenerative disc disease, piriformis syndrome, pregnancy or trauma etc. 

According to Ayurveda, Sciatica is caused due to impairment in Vata i.e. the dosha responsible for the functional ability and movement of the body and also in some cases due to impairment in the Kapha i.e. the dosha that is responsible for body fluids and lubrication. Ayurvedic herbs that improve the symptoms of Sciatica are:

1. Babunah is also known as Bitter Chamomile. Not only is it used to relieve and reduce the pain faced by a sciatica patient, but it is also used for treating problems such as rheumatism due to the advancement of age. Compressed bitter chamomile flowers are prescribed for sciatica.
2. Guggul is also known as Indian Bdellium. Since guggulu is well known for its anti-inflammatory properties, it relaxes the sciatic nerves.
3. Rasna is also known as Vanda Orchid. Intense or agonizing pain due to the sciatic nerve issues can be reduced by this ayurvedic herb due to its anti-inflammatory properties. 
4. Juniper oil is extremely helpful when massaged onto the thigh muscles with firm strokes or pressure. It is used extensively in massage therapy for treating sciatica since the extent of reduction in sciatic nerve pain is tremendous. 
5. Jaiphal is also known as Nutmeg. After being mixed with sesame seeds oil, nutmeg is coarsely powdered and then fried till it turns brown. This is then applied to those areas where the sciatic pain is intense for instant relief.
6. Kumari is also known as Indian Aloe. Properties of Indian Aloe are extremely helpful in treating lower back ailments such as sciatica and lumbago.
7. Shallaki is also known as Boswellia or Frankincense. Containing anti-inflammatory properties, shallaki is applied externally to get relief from sciatic nerve pain. 

Ayurvedic preparations such as yogaraja guggulu, Vataganjakusha, Saindhavadi taila are also very useful in treating Sciatica.
