I was diagnosed with SLE and RA and MCTD about 4 months ago. I have mini flares from the RA once in awhile but they see to go away after a few hours of rest and pain killers. On Wednesday however, my whole back, shoulder, arms, and neck Spasmed all day. On top of that i was nauseous and had stomach knots and my joints flared up. Unfortunately, i worked a 11 hour ahift that day so i really didnt get to relax till i got home. My mom gave me a muscle relaxer but that didnt help. I stayed home on Thursday (the next day) but i still had pains all over. On Friday (today, like right now) im at work. My back and joints feel like ive finished a intense workout. Can these be flares? Is there such a thing of mini flares or one or two day flares? Someone told me flares last about a week or more.
