Okay so I was doing the splits and I was almost all the way down to the ground with out a problem next thing I know, I went down a little farther and my front leg behind my thigh near my butt popped a lot and it's hurts really bad where I move it, I'm in horrible pain.
Dear Friend.Hi , I am Dr Anshul Varshney , I have read your query in detail , I understand your concern.You might have got a muscular/ ligamental tear over there.However, if pain doesn't subside you should get Xray also to rule out possibility o fracture.At present i advise you following:1. Bed Rest2. Local Hot Fomentation3. Application of local pain killer gel like Volini gel.4. A pain killer like Tramadol and Acetaminophen like Ultracet in moderated doses.Also you should see an orthopaedician for proper examination and diagnosis.This is my personal opinion based on details available here.  If you still have any query you may please ask me.Stay Healthy. Dr Anshul Varshney , MD
