I'd suggest that you contact your Rheumy first thing this morning. Sounds like your body is in a flare whether it be a fibro or lupus flare up. I know that they haven't formally DX'd you yet.
Try to rest as much as you can until you can see the Rheumy.
I wish you a Merry Christmas and I hope that you're feeling better soon.
DX- RA, Lupus, Fibro, LGL Leukemia, Obstructive & Central Sleep Apnea, Pulmonary Hypertension, Bells Palsy, Gastroparsis, Blood Clots, Glaucoma, Chronic Pericarditis & Pleurisy, Severe Anemia. Way to many medications to list.
