Yes, this seems to happen to me too. Especially when it's such a drastic change in weather as has been the case here in PA lately. Three weeks ago it was in the teens at night and mid- thirties during the days. The past 5 or so days though, it's been about 50 at night and up to 75 degrees during the day. Now starting tonight and into Tuesday it's supposed to get close to 20 degrees cooler and rain. My body has definitely been effected by it since I've been in a flare for the past few weeks and was on IV Solumedrol last week x 5 days and am currently doing the tapering down doses of Prednisone. You are not alone!
