I have had both vomiting and full body temperature regulation issues since maybe a year or two post RSD??? I am on Estrogen, but alas, this has not solved "hot flashes". I still get chills as well, but not with as great of frequency as the earlier years. Meds can be a factor for both, so it's tough to know what is always going on.
My stomach pain and vomiting made me (additionally) miserable for years, because it was frequent, but not constant, and completely unpredictable. For me, changing how I eat, had resolved the stomach issues. Last week, for a variety of reasons, I started eating more bread and generally less well, than I had in the past year and a half. Sure enough, I started vomiting with almost no warning. Maybe my issues are not RSD related... Maybe my meds aggravate an underlying issue? Following the 4 F's diet closely isn't always fun, but my stomach, energy levels, swelling and pain levels are definitely better for it.
Congrats, btw! Grandma Alt?
