The tendon pain behind the bend of the leg may be related to overwork, cysts, lumbar spine lesions and other disease factors.
1. Overwork: prolonged standing, squatting or strenuous exercise, resulting in muscle strain and subsequent pain.
2. Cysts: cysts in the popliteal fossa area, due to cyst compression of the tibial artery, tibial nerve and the surrounding subcutaneous nerves, there will also be hamstring pain; inflammatory factors in the joint cavity to reach the back of the joints, stimulate the joint capsule and other tissues at the back of the popliteal fossa, resulting in pain in the popliteal fossa.
3. Lumbar spine lesions: such as lumbar disc herniation and other diseases, lumbar spine lesions stimulate the nerve root, lower extremity radiating pain, often radiating to the back of the knee joint, causing hamstring pain after bending the leg.
Generally due to overexertion caused by the hamstring pain, can be relieved after rest; if non-exertion caused by persistent severe pain, you should go to the hospital in a timely manner to improve the examination, standardized treatment.
