Knee pain is characterized by a feeling of pain in the knee joint caused by injury or overuse. The knee joint consists of small bone structures, the kneecap, supporting ligaments and cartilage of the knee. This joint bears the full weight of the body, which makes it very vulnerable to injury.

Causes of knee pain

Knee pain is usually caused by injuries to the knee such as exposure to a direct force on the knee, abnormal twisting of the knee or falling on your knees. Some causes of knee pain are -

• Knee strains and sprains - Overworking the knee joints can damage the tissues of the knee joint resulting in knee sprains and strains
• Osteoarthritis - it is condition where the protective cartilage around the kneecap is damaged, resulting in knee pain
• Bursitis - Excessive movement of the knee or kneeling down for extended periods can irritate the bursa (a fluid sac below the skin above the knee joint) that causes swelling and pain, thereby giving rise to this condition
• Gout - This condition is characterized by the accumulation of uric acid in crystal form around the knee joint, causing inflammation and pain
• Tendon disorders - Tendons connect the muscles to the bones, and overworking the knee can cause the tendons around the knee to become sore and painful
• Kneecap dislocation - Injuries may cause the kneecap to shift out of its position, this causes swelling and pain in the knee joint

Symptoms of knee pain

Severe knee pain can restrict movements such as walking or standing. The symptoms vary according to the extent of the damage suffered by the knee. Most common symptoms of knee pain are problems in climbing stairs, inability to extend the knees, limping and swelling of the knee joint. In some cases, knee pain may also cause fever.

The sciatic nerve is one of the largest nerves in the body. It goes from the lower back all the way down to the base of the leg. When there is a disorder associated with the sciatic nerve, it is known as Sciatica. 

Sciatica, however, does not necessarily need a surgery or a very elaborate procedure to fix the problem. Most commonly, it is treated simply by practicing a number of simple exercises. Here are some of the most common exercises prescribed to treat Sciatica:

1. Reclining Pigeon Pose: There are three main forms of the pigeon pose. These are sitting, reclining and then forwarding. It is recommended that if you have very recently started your treatment for Sciatica, then certainly you should go for the reclining pose. In this pose, you are supposed to hold your left leg in the air at a right angle to your back. Then, hold your ankle against the knee. Finally, repeat this stretch with the right leg as well.
2. Knee to Opposite Shoulder: In this stretch, the starting position is on your back side. You have to have your legs out and feet upwards. From this position, try to bring your right leg towards your left shoulder. Hold this for 30 seconds and then release and relax. Repeat this activity three times and repeat the whole procedure with your other leg. Only take your leg as far as it goes.
3. Sitting Spinal Stretch: At the start of this exercise, sit on the ground with your legs going straight outwards and your feet flexed in the upward direction. Pull your left knee and put it on the outside of your right knee. Finally, place your right elbow on the left knee, so that your body turns to the left. Hold for 30 seconds and then relax. Repeat the procedure with the other knee.
4. Standing Hamstring Stretch: Put your foot on an elevated surface such that it is above the floor, but not above hip level. Flex your toes forward such that your feet and legs are nearly in a straight line. Bend as far towards the foot as possible. However, do not stretch so far that you feel pain. Finally, repeat this procedure on the other side after release. If you wish to discuss about any specific problem, you can consult a Physiotherapist.
