Hamstring tendinopathy
The hamstring muscle is made of three muscles, which all originate from the bony prominence in the middle of the buttock. You can feel this bone under your buttock in sitting position, if you put your hand under the buttock, i.e. the bone you sit on. This area where the tendon originates from can become painful/sensitive which we call proximal hamstring tendinopathy.
Our tendons (which attach muscle to bone) undergo various stress and strain during our day to day activities. They adapt and recover from these on a daily basis. When the demand placed on these tendons exceeds their recovering capability they can become painful. We understand that multiple aspects affect the demand as well as the recovery of these tendons. The common ones being age and the demand placed on the tendon. If the demand we place on the tendon is higher than its capacity to recover if not given enough time, the tendon can become painful. As we get older the recovery of the tendons slows down too. We also know that stretching and compression of the tendon worsens the pain.
