When I sit and think about it, it is INCREDIBLE how the symptoms vary in intensity, length of "attacks", and how different areas of my body have suffered at different times. For example, two months ago I was having severe surges and pressures on the sides of my head, dizziness, and constipation, and a metallic taste in my mouth. As of late I have had AWFUL,AWFUL chest pains and the worst angina of my life,- easily. The symptoms can then vanish for half a day, acrually to the point where I feel almost totally healthy, and return without warning with frightening severity, so bad that I feel on the verge of rushing to the ER and that I might actually collapse or die. I almost can't believe the reactions in my own body, and the off and on, off and on systemic affects that are occuring.
