The location as well as the severity of knee leg pain may vary. This is because it depends on the cause of the problem. There are various signs and symptoms which usually accompany knee pain. These include swelling and stiffness, besides redness and warmth to the touch. There may be weakness or instability besides popping or crunching noises. An inability to fully straighten the knee is another symptom of knee leg pain.
You need to see a doctor in case you can’t bear weight on your knee or you have marked knee swelling. You need to consult a doctor in case you are unable to fully extend or even flex your knee or you are able to see an obvious deformity in your leg or knee. Your knee leg pain may be severe in case you have a fever, besides redness, pain as well as swelling in your knee.
Your knee leg pain can be caused by injuries, mechanical problems, or due to various types of arthritis as well as other problems. The injuries associated with knee leg pain can affect any of the ligaments, tendons or even the fluid-filled sacs which surround your knee joint and the bones, cartilage and ligaments which form the joint itself.
The common knee injuries include ACL injury, which refers to the tearing of the anterior cruciate ligament (ACL). This is one of four ligaments which connect your shinbone to your thighbone. An ACL injury is common in people playing basketball or doing downhill skiing. This is because it’s closely linked to sudden changes in direction.
Torn meniscus is another reason for knee leg pain. The meniscus is made of tough, but rubbery cartilage. It acts as a shock absorber between the shinbone and thighbone. It can get torn in case you suddenly twist your knee while you are bearing weight on it.
