Update from having pop in hip. Started seeing an osteopath for the sciatica. Two sessions in and already helping. Also, pulled my hip every which way and said its solid. Phew. Doing gentle exercises that get better results than physio. Very easy to do. Said physio exercises pushed me too far too soon.!!! Physio told me seated bike was useless for hip replacement, osteopath has me using twice a day. Got to build my muscles back up. Can already feel thigh muscles coming back. Will keep seeing him weekly for a while, then have top ups when needed. Anxiety over hip gone. For me personally, I have achieved more progress in 2 weeks than ever did with physio.
