Autoimmune flares: questions people ask
Which autoimmune conditions does this cover?
Feelcaster doesn’t diagnose anything. You can watch for lupus, Sjögren’s, scleroderma, multiple sclerosis, psoriasis, Hashimoto’s, Crohn’s or colitis and more by name, or choose Autoimmune flares if weather seems to play a part.
How does Feelcaster learn my pattern?
Check in or log how you feel, especially on hard days. Each log keeps the weather from the hours before it, and the Report tab shows what your bad days have in common.
