I developed severe osteo-arthritis in my hands about 5 years ago. It took me over a year to get referred to a consultant. It wasn't doing injections that was my problem. It was squeezing the washing-up liquid, lifting anything heavy in a bag with handles, doing all the ordinary things you have to do to look after yourself or cook a meal. I now have cortisone injection in my basal thumb joints when the pain starts to increase. It works well, but send your BS up like a sky rocket ! You need extra insulin for some days if you're a type 1. The injections are also painful in themselves, so not an easy answer. Are you sure it's osteo-arthritis ?
