New to RA

Hello, I'm currently writing with one hand and it's my non dominant one.I have chronic kidney failure and I go to dialisys and this now is new to me.Aside from my Chrons disease and my psoriasis this is causing a lot of pain.It first started with my fingers,with my worst pain being in one of my pinkies and then a small noticable pain the elbow of my dominant hand.I keep repeating dominant and non dominant because I have a fistula for dialisys on my non dominant one which means that I cannot really use it or lift heavy things.So over the course of a week I think the pain in my elbow has been barely noticable, my pinkie pain is no where I think where it was and I would wake up each day with a new finger slightly swollen (crooked) and in pain.So I wake up one morning with my dominant hand in extreme pain in the elbow.So bad I can't move my arm downways and upways only sideways.I cant perform daily tasks and I'm in big pain almost severe u would say I think even when I'm not moving my arm I think.I take a low dose Prednisone because of my other conditions and upping dosages is out of the question for me.Side effects are way too dire for me.And I'm at a holiday with my family so I can't really receive treatment.Ill drink painkillers and hope I wake up with less pain.Also I'm 19 years old and any tips for pain and no meds to fix it?
