I've got what the hospital think is a "stretched" nerve in my shoulder - CT, Xrays, MRI all failed to show anything up.
I've had Codeine Sulphate, Co-Codamol and Gabapentin (none helped). The GP has now prescribed Pregabalin, but looking at the side-effects, mainly the ones affecting mental health (I'm already on antidepressants), I don't want to take them. The doctor is possibly going to use a steroid injection, in 2 weeks' time. I've had the pain every day since July.
This is slightly off-topic, but have you tried physio?
I had a mysterious pain in my shoulder and arm for months. After x rays and MRI scan, I eventually had physio and was taught exercises to rebalance my spine because my posture isn't good. The exercises really did help and when I get pains, I know what to do.
