First, I was tested for GCA last month and got a clear result. I've had PMR for 18 months and I have finally been successfully weaning to lower doses of prednilosone. I was in the 6-7mg range for several months, as pain would return.. you know the drill. I finally got down to 5 mg for about 3 weeks, then 4 and stayed there for a month... I felt great. Best I've felt since diagnosis. Doc told me on weds to cut back to 3 mg for a month. So, day 1, Increased soreness but nothing severe. Day two night (I take in am) I got the worst headache I have ever had. ALL NIGHT. Couldn't sleep, ice didn't help (has in the past for headaches) but this one had me retching throughout the night. It was like I could almost SEE the pain. Today I'm feeling like I was in a wreck. Achy and sensitive but not in serious pain. Stiffness and ache increased. Totally drained.... in my research I don't find headache listed as a withdrawal side effect. Can anyone inform me differently? PMR Pro or Lady Dorset?
