I have Rheumatoid Arthritis (since I was 28, am now 59) and I was diagnosed with Polymyalgia Rheumatica last year (Oct, 2012) and have been on Prednisone since then (7 - 10 mg per day). Everything was in control until about a month ago when my hands became very stiff (RA symtom) and then last week I got a splitting headache (left side, over my left eye, along the left side of my head and at the left back side of my head). During Oct, 2012 this (headache) was how my Polymyalgia Rheumatica started. Should I increase my Prednisone or what?
