Since Dec. '07 have had both shortness of breath on very mild exertion (taking shower), and blood pressure that sky-rockets to 173/93 on mild exertion, like mopping the floor for fifteen minutes, then it goes back down when I sit for a while. I also have mild chronic headaches that are helped by ice bags. Chronic, fleeting dizziness that sometimes seems positional, but not always. Have seen cardiologist, neurologist and am currently seeing a rheumatologist, who clains my elevated ANA may be a false positive. He is running more blood tests. Will know in two more weeks. Does this sound like any type of autoimmune disorder. I have not been able to work, or do even simple tasks that I enjoy doing for over six weeks. Any info is appreciated.
