As others have said, a discussion with your GP about the pain is sensible, to exclude other causes. I need a total hip replacement and have had both groin and abdominal pain. However, following the advice of the excellent orthopaedic surgeon I saw in the summer, I was prescribed a regime of simple pain relief - regular paracetamol and ibuprofen 3 times a day, with a small dose of codeine added to the night time dose. Plus a medication to protect the stomach lining, taken before breakfast. (This amount of regular ibuprofen should be taken under medical supervision as we are older and there can be unwanted side effects. Occasional use is fine). The difference in my pain levels was amazing after two weeks and I was able to reduce the dose, again following a chat with the GP. I sleep so much better now. There was obviously inflammation there which has reduced. I still need a hip replacement but can live with the discomfort now. I had dismissed the simple analgesia option as I thought that with the degree of pain I was experiencing, it wouldn’t be effective. I was wrong!
