Motion Sickness

From: Jennifer



After reading some of the posts here, I now feel like I know what's been wrong with me all these years.

These symptoms occur: Feeling faint and listless, sweating, blacking out, nausea, getting REALLY warm.

The symptoms occur when I lose a good deal of blood (usually during donation or blood work as mentioned in my previous post), flying (mentioned in my previous post), riding roller coasters, when I have severe stomach cramps, ride in the car too long or get too hot (I thought it was heat stroke).

My normal blood pressure is usually 90/70 or 100/70.

I weigh more now than I did when I had my first episode (giving blood), but my blood pressure is the same. In fact, if my blood pressure gets too high (it went up some during my pregnancy) I get severe headaches, bloodshot eyes.

I now realize that my symptoms for seemingly unrelated events could be traced back to VV, though I've never been diagnosed. A NP told me about it years ago, and I never connected the episodes until now.
