Great Job Ginny!! Very informative. Yeah those buggers can happen. Mine come and go after years in between episodes. Also watch for those seizures that can sometimes come with the mini-strokes. They were mild for me but brought on a lot of havoc because I wasn't aware I had them when I was driving. A few tickets later... luckily only mild accidents. There weren't any warning signs with the petite seizures. Just cautionary advice.
Veronica - My doctor just told me to take asprin religously and that ended up working out the problem. Not sure why they elected not to use the Heparin, but you should look into preventative medicines until they find the cause of the TIAs. Also RESTING and deep breathing exercises helped some I noticed. They seemed to come on more with activity and stress. If they come on back to back or you feel/look very ill rapidly (white in face/lightheaded, etc.), get to the ER and/or put family, etc. on alert. When I got the dementia they came on very rapid and then a big one where I lost consciousness. My friend also ended up with a major stroke in a similar way. (I have CNS Lupus and she had Kidney Lupus).
I hope you get treated early to avoid any potential serious consequence like my friend and I went through. The doctors wouldn't listen to me and my friend's came on very suddenly so we didn't have your luck. Sometimes the best thing is a warning then early treatment. Kind of an odd blessing I guess. I wish you the best - Kristin
