last night a woke up in the early night with what I would call severe chills. My entire body was shaking and my teeth chattering so badly they ended up hurting. the intense shivering could not be stopped for about 10 min despite climbing into a bed and putting 4 blankets on top of me.

I do have high blood pressure, controlled with lisinopril/hydrochlorothiazide, atenlonol, low dose asprin, and amlodapine.
