This are some of my symptoms: *Short-term memory or concentration problems *Sore throat *Multi-joint pain without joint swelling or redness *Muscle pain *Headaches of a new type, pattern or severity *Non-refreshing sleep *Poor sleep *Brain fog *Increased thirst *Recurrent infections *Exhausting after minimal exertion I know that many of this are to symptoms of POTS, but not all. Could I have both? I have the Sjogren's Syndrome too.
