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.

Knee pain or injuries are very common and have numerous causes. Knee pain can emerge from delicate tissue wounds like ligament sprains and muscle strains. Bone conditions like knee joint pain, Osgood Schlatters, and biomechanical dysfunction can also cause knee pain. Treatment can include basic knee mobilization techniques, taping, massages or knee strengthening exercises completely through a careful recovery method after knee replacement or reconstruction.

Physiotherapy can help you overcome the pain and increase your strength and flexibility. A physiotherapist can suggest you a number of treatments and also help you understand your issue and get you back to your everyday routine. Physiotherapists are said to be successful in getting rid of the source of the knee pain by diagnosing a cause. This includes tightness around the knee and treating it with stretching and exercises.

Following are some of the exercises a physiotherapist might generally recommend for knee pain:

Hamstring stretch: Stretching keeps you flexible and increases your scope of movement, or how far you can move your joints in different directions. It additionally helps you reduce your chances of injuries and pain. Continuously warm up with a five minute walk first. Lie down when you are prepared to stretch your hamstring. Circle a bed sheet around your right foot, use the sheet to pull the leg up and hold for twenty seconds and then lower the leg. Repeat twice and switch legs.
Calf stretch: Use a chair for balance. Bend your left leg. Step back with your right leg and gradually straighten it behind you. Press your left heel toward the floor. You should feel the stretch in the calf of your back leg. Hold for 20 seconds. Repeat twice and then switch legs.
Straight leg raise: It helps build muscle strength to give support to the weak joints. Lie on the floor. Twist your left knee, foot on the floor. Keep the right leg straight, toes pointed up. Tighten your thigh muscles and raise your right leg.
Quad set: With these, you don't raise your leg. Just tighten the thigh muscles, also called the quadriceps, of one leg at once. Begin by lying on the floor. Keep both legs on the ground, loose. Flex and hold the left leg tense for five seconds and then relax. Do three sets of ten repetitions. Switch legs after every set.
Cushion squeeze: This move strengthens your legs from the inside so that they can support the knees. Lie on your back, both knees facing inwards. Place a cushion or a pillow between the knees. Press your knees together, squishing the cushion between them. Hold for five seconds and then relax. Do three sets of ten repetitions. Switch legs after every set.
Heel raise: Stand tall and hold the back of a seat for support. Lift your heels off the ground and rise on the toes of both feet. Hold for three seconds. Gradually lower both heels to the ground. Do three sets of ten repetitions.

Are you experiencing a swollen and painful joint and are looking for an effective way to treat it? You can choose homeopathic treatment, which is considered to be ideal for joint pain and inflammation, as it does not have any side effects. When a joint swells up, gets inflamed, or damaged due to an injury, joint pain is experienced. Aging and several medical conditions such as gout, osteoarthritis, rheumatoid arthritis, general injuries, and sprains are common causes of joint inflammation and pain. A wide range of homeopathic medicines is used for the management of joint pain and inflammation.

Here is a list of the top homeopathic medicines used for this condition along with the symptoms when they are prescribed for use:

Rhus Tox- This homeopathic medicine is very effective in treating joint pain. Both acute and chronic joint pains are cured by this medicine. It is used when a patient experiences marked stiffness in the joints along with intense pain. The medicine treats all kinds of joint pains, starting from rheumatic reasons to injuries caused due to overexertion. Usually, the joint pain gets better with movement and worsens if you are immobile.

Sanguinaria Can and Ferrum Met- Sanguinaria Can is used for treating joint pains which occur in the shoulder. It is most effective in the case of right-sided shoulder joint pains. The right-sided shoulder of the patient may feel stiff and the pain worsens with any kind of motion. The right shoulder joint pain increases during the night. On the other hand, Ferrum Met is used in the case of left-sided shoulder pain. The patient experiences stiffness and cracking in the left shoulder joint along with great pain. The pain increases if you raise your arm and with any kind of movement.

Homeopathic Medicines for Joint Pain & Inflammation 

Knee replacement can be extremely painful. Previously, opioids or narcotics were administered for pain relief. But excessive addition of opioids is not exactly effective for controlling pain. 

Multimodal pain management has become an important part of the perioperative care of patients undergoing total joint replacement. The principle of multimodal therapy is to use interventions that target several different steps of the pain pathway, allowing more effective pain control with fewer side effects. Many different protocols have shown clinical benefit. The goal of this review is to provide a concise overview of the principles and results of multimodal pain management regimens as a practical guide for the management of joint arthroplasty patients.

Multimodal denotes administering two or more than two types of medications that work with different mechanisms. The following are the techniques used:

Pre-operative Femoral Nerve Block: Prior to the surgery, a catheter is placed beside the femoral nerve for blocking it. This nerve is located in the upper thigh. Medication is delivered through the catheter for the nerve to be numbed for 24 hours. Thus, pain signals to the brain are blocked. This method reduces the use of narcotics and the consequent side effects.

Patient Controlled Analgesia (PCA): This method is also known as  Pain Pump . An intravenous pump is used to administer pain relief medications, such as oxymorphone or morphine, after the surgery. The control button of the machine could be pressed, by the patient for 6 to 10 times per hour. The machine is used for two post-operative days.

Oral Medications: The oral medications include Non-Steroidal Anti-Inflammatory drugs or NSAID; such as Celebrex which is similar to aspirin, structurally. Alternatively, acetaminophen, such as Tylenol or its equivalent composition, can also be used.

Acetaminophen: It acts on the Central Prostaglandin Synthesis and relieves the patient of pain through multiple mechanisms.

Epidural Analgesia: It produces lower pain scores and involves less time for achieving physical therapy goals. However, this is subject to side effects such as dizziness, urinary retention and itchiness.

Gabapentinoids: These medications include membrane stabilizers such as Gabapentin and Pregabalin.

The objective of multimodal treatments is to provide quick relief to the patient and immediately so. Earlier the rehabilitation, more successful will be the knee replacement surgery.

Multimodal Pain Relief After Total Knee Replacement

Knee pain is one of the most common and painful ailments that can limit mobility. Injuries can result in cartilage or meniscal tears or sprains too. Obesity is another reason because of which knee pain is on the rise. Also, regular wear and tear of ligaments and tendons around the knees due to old age is another cause. These days, with reduced physical activities and sedentary lifestyles, the rate at which knees are wearing out has also become accelerated. Whatever the reason, a correct diagnosis followed by prompt treatment can help. Over the years, physiotherapy has been playing an important role in treating knee injuries. Whether to supplement the various drugs to reduce pain and inflammation or to avoid surgery, physiotherapy has helped many and its popularity is growing every day. Here are some ways that physiotherapy can help reduce pain.

Improve flexibility of tendons: The knee cap is an area where there are lot of tendons and ligaments, coordinating to enable movement. Careful exercising can ensure that the flexibility of tendons and ligaments is improved, thereby making your knee movement easier and less painful.
Improves blood supply: As we all know, proper movement requires good blood supply. Exercising with special focus on the knee ensures that blood supply is improved, and thereby the supporting ligaments and tendons function optimally.
Enhances the knee cap function: The knee cap is that portion which joins your thigh bone to your calf bones. This is prone to slip out of place, especially with arthritis and injuries. This can be painful and limit movement to a great degree. Focused exercises aimed at improving knee cap function will ensure that the knee cap has a wider range of function, and does not slip out of its socket easily.
Reduce rigidity: Once you start physiotherapy, you will feel your knees getting more flexible. The rigidity that had set in as a result of injuries and/or old age will also reduce over a period of time.
Slow down the wear and tear: When you start physiotherapy after knee damage, continuing the exercise routine, of course with expert guidance, can reduce the pace at which further damage might happen. A word of caution though. Be sure to consult an experienced physiotherapist before you begin. Exercising in a bad manner can do equal or more harm than the original injury or old age itself.

Knee Pain and Physiotherapy

The bones are the bits and pieces which form the framework of the body. Each bone is placed in the correct position to give your body the structure it has. It is of utmost importance for you to have healthy bones so that the structure or frame of your body is maintained. A lot of times, due to the stress of your daily life, you tend to neglect the health of your bones. But remember that if you want to have a fit body, you will have to keep your skeletal system fit as well. Here are a few tips on how to keep your bones healthy:

1. Family history: Having a knowledge of your family history is extremely important as there may be cases where you might suffer from a particular disease which is hereditary. If your family has a history of osteoporosis, there is a high chance of you suffering from it. 

2. Increase your regular calcium and vitamin D intake: Calcium is extremely essential for your bone health. If you want your bones to be healthy and strong, you need to take a regular calcium dose in order to achieve that. But there is a catch to this. Although you might have food containing calcium every day or take calcium tablets, it won't be helpful until you also get a supply of Vitamin D. Vitamin D helps the bones to absorb the calcium.

3. Maintain a healthy bone density: To do this you need to eat food which will supply you with vitamin K. Vitamin K boosts bone density by enabling the body to make proteins required for healthy bones. Vitamin K also helps the bones absorb calcium just like vitamin D although this function is not predominant for vitamin K.

4. Exercise: The secret to healthy bones is exercise. The more you exercise regularly, the fitter your bones and muscles will be. Regular exercise helps to keep bone problems at bay. Leading a sedentary lifestyle heightens the risk of suffering from osteoporosis. It can also mess with your bone density and weaken your bones. Hence, exercise regularly for healthy bones.

5. Cut down on your caffeine intake: Too much of caffeine can mess up the calcium absorbing power of your bones. If you have more than two cups of coffee every day, your bones will gradually become weak.

So, if you want to remain as fit as a fiddle, then try these tips out, and you will not complain.
