A member asked:

Doc told me had low blood pressure other day now very tired also have rash on back and arms very itchy for 2 days little and big bumps is it related?

A doctor has provided 1 answer

Low BP: It would be nice to be able to look at a rash to render a better judgement about it, however, big blotchy rashes with itching generally suggest urticaria. Urticaria causes vasodilation of the blood vessels which can lead to a lower BP
