Does anyone have any issues with exercise intolerance? All of the doctors have said over and over again to me how important it is for me to exercise in order to feel better. However, each time I exercise, I feel awful the rest of the day. The following day, I end up extremely light-headed and nauseous all day and have a difficult time standing up for very long. I had an exercise stress test, and they had to stop the test because I got really dizzy and came close to fainting. It turns out my bp doesn't increase as much as it should with where my heart rate gets to. As the test continued and intensity increased, it started to fall. It has been recommended to me that I do no weight-bearing exercises and stick to things like a recumbent stepper or cycle. (and of course hydrate, hydrate, hydrate! ) I've been following their directions for intensity and time, but it seems to be making me feel worse rather than better. It's tough because I've always been a runner...I miss being able to exercise how I used to. Has anyone else dealt with this? If so, did it get better with time or does exercise always make you feel bad? Thanks! Heather
