I would encourage you to call your clinic or urgent care/ER if you are having these symptoms in this weather as you are right you may be dehydrated. I would guess your on medications which could factor in with the heat spell your having.
It could be anxiety but do make the call to see what your Dr. suggests you should do. Also pedialyte and Gator Ade are good to have on hand when the weather is so hot.
Let us know how you are doing as we care.
Kindly,
Kitt
