While doing a leg split, left foot forward in the sand,I went too far and heard a pop. Had pain in left butt, and all the way down back of leg to toes. It hurt to walk.I went for a gentle swim which was ok.Now 2 weeks later, it hurts some in left butt,hip and back of thigh to knee.I previously hurt left sciata which was okay til now.I can use left with small amount pain. It hurts to sit awhile on it.
While doing leg split, flexion occurs at hip and extension at knee joint. It causes stretching of hamstring muscles which are situated at posterior part of thigh. Sudden stretching can cause severe spasm in these muscle group and sometimes it may lead to tear of muscle at its origin (these muscle originates from social tuberosity, the bone on which we sit). Rest, ice , muscle relaxants and analgesics such as ibuprofen may help you. Hope this answers your question.
