Knee pain, which is very common and affects up to half of all athletes, is often caused by damage to ligaments or cartilage tearing, notes WebMD. Bone chips are another cause of pain in the knee. They occur when an injury to the knee breaks off small pieces of bone or cartilage, which become stuck in the knee. Sometimes, the kneecap can become partially dislocated, or tissue called plica may become irritated with overuse, causing knee pain.

Leg pain is normally caused by overuse or damage to the muscles, ligaments and tendons, according to Mayo Clinic. In some cases, leg pain is caused by a problem in the lower spine, blood clots or varicose veins. Some other common causes of leg pain include deep vein thrombosis, gout, a hamstring injury, ACL injury and fibromyalgia.
