Thank you Joy. I have never heard of MSA.
I have had blood pressure issues since my early 60’s. It appears mine are heredity from my father who died at 70 from a heart attack. I had a mild one in July and they have me on meds. My doctor said he would do a new valve if they had one that he needs for my problem. But, that one is in use in other countries, but not approved in the states.

I am with you on your answer. Glad someone raised the discussion on the hot and cold changes that PD. may cause.

I go from to cold, to hot and sometimes just the same as everyone else around me. Never know 🤔😊

cont. I am hot with AC on even though it is a cool day.

I occasionally feel like I'm too hot or too cold for the outdoor temperature. I was tested for cryoglobulinemia; it was negative. I am hot now withair
