I am 46 yrs old. Very good health, physically active. Last night I xperienced sudden chest pains, dizziness , drymouth, and a metallic taste in my mouth. I felt like I was going in and out of conscienceness. Everything I pulled up refers to a panic attack, but that would not make sense, there would be no reason for that. Today, I physically feel weak, as if my body experienced something. I have no appetite, and extreme dry mouth .
