Since I suffer badly from osteo-arthritis, I empathise. Over the years, I have had several steroid injections into my joints and had to "grin and bare them." Eventually the right shoulder was repaired surgically and the left one will be sorted this year. As for the pain in my hips - I had both of them replaced in 2011. Your procedure can be done under local anaesthesia but only the skin area is affected so it may be a bit uncomfortable. If you have concerns - talk it through with your clinician. Hopefully, though, you will become pain free soon.
