Welcome to the lupus forum, I'm sorry that you need to drop by though. You have a lot going on between everything you already have.
As you know AI diseases are so hard to DX. Is it possible that you may have lupus, maybe. Have you looked at the requirements to be DX'd with lupus are? You must have 4 of the 11 symptoms.
The MS, RA, Fibro, and Lupus all seem so alike it's hard to sort them out. It took my Dr's 13 years before they said yes it's Lupus. I truly believe that all the time I went untreated has affected where I'm at now.
I hope that you can see your Rheumy quickly and they will be able to answer your questions. I pray it's NOT Lupus, you have plenty to cope with. If you have any other ?'s please ask. Good luck and take care.
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.
