I am having a great deal of shoulder pain caused by bone on bone arthritis. I am on Tramadol, 50 mg. tablets, 3 x daily for fibromyalgia pain. I also have controlled A-fib and take Sotalol, 120mg. tablet. 2 x daily, as well as Warfarin, Lasix, Synthroid and a few supplements daily. My question is may I take Oxycodone for a day or two instead of the Tramadol, to cut the shoulder pain until I can get in to see my orthopaedic doctor for a cortisone injection? I am having a hard time just getting dressed in the morning, etc. I also began to see an acupuncturist in the hopes of alleviating the shoulder pain for a few months until I can undergo a shoulder replacement. Do I need to worry about an interaction between Sotalol and Oxycodone? Do I have to worry about Oxycodone causing an flare up of my well-controlled A-fib?
