In the few long months that I have been suffering with anxiety I have only noticed this on me one time which was the other evening. I felt as if I had a fever my face was red, and my husband said i look like I have high blood pressure. I thought all god........I have high blood pressure, i'm going to have a stroke. I've never had high blood pressure even when I had a panic attack and was in the ER it was normal. It's always been normal even when I am highly anxious. I had a few good days the other week and when my symptoms returned it was a whole different set almost. Now I've been getting the hot feeling, sort of like a fever from the shoulders up. I get tension headaches and i've never had them before. I feel like I'm going through menopause but i'm only 33 so i don't think this is the case. I'm right there with you and I believe this is just a symptom of anxiety. I'm going to my family doctor next week cause I have a couple questions about some new symptoms. I just want to ease my mind. Maybe you could do the same just to ease your mind. My doctor convinced me in the early stages nothin was wrong with my heart, now I need convincing it's not my brain.
