This is characterised by pain in the upper part of the back of the thigh, just below the buttocks. It is a condition that frequently affects runners, although it can be suffered by all athletes involved in running, jumping and strengthening of the lower body. Its incidence increases as we age and it is more frequent in females due to changes in collagen.
It may originate from a proximal hamstring tear that went unnoticed or was not treated correctly. However, in most cases, it is a typical overuse injury. This overload generates micro lesions in the muscular insertion that progresses over time.
