50/50 ball had most of the same symptoms as yourself. Went to Roy Spence in Ulster Independent, got MRI which showed up problem in both my hips. Was referred to Prof. Cullen and I got an MRI arthogram, which is an MRI but with a coloured die injected into the hip. Result was a torn labrum in the hip joint. At 35 I didn't fancy an operation (was being referred to Richard villar in England for the operation) that couldn't guarantee it would fix the problem, so I quit the football and I did an extensive rehab programme which settled the problem. It flares up now and again but I couldn't go back playing football regularly. A lot of hip based exercises are a no no now, ie. squats, thrusters, mountain climbers, burpees etc. God knows what my hip will be like in 5 years time.
