Following months of symptoms and different diagnosis, my GP has decided to start me on Sulfasalazine with 20mg Prednisolone and monitor every 2 wks. Has anyone else been treated this way. Also is it possible that i have a different dissorder to RA. What other conditions improve with steroids. I was previously (2003) diagnosed with Fibro Myalgia. Could it be a flare up? How can they tell the difference??
