I know you posted this a couple months ago and hopefully have found a way to ease back into exercise. I just wanted to tell you that I went through exactly what you're describing about a year ago. I started having vasovagal syncope episodes that went on for several months and during that time, my docs were telling me not to exercise. I even had to reduce my work schedule for awhile until they got it under control. When they gave me the go ahead to exercise, I was nervous to even walk around the block. I would tell my husband exactly where I was going and told him to come find me if I didn't come home in 30 minutes. There were several times when I felt dizzy and lightheaded and would need to stop.

After seeing a specialist, he told me one of the best things people who have vasovagal episodes can do it exercise to strengthen your legs. His recommendation was to get back into it slowly and do 15 minute increments to build back up to longer times, and also to sit down when you're done exercising, drink plenty of gatorade, and try to eat something salty. I started back on the treadmill, increasing my walking speed and time until I felt comfortable running again. Same with the bike and elliptical. For the most part now, I exercise as much as I did before the episodes and back into zumba, boxing, and spinning. Every once in a while, I'll feel a little dizzy and when this happens I just stop and sit until it passes. But this is very rare.

I totally understand your frustration but for me, this was not forever and hopefully it won't be for you either. A couple things that might help is to start by going to the gym or for walks / runs with a friend or relative until you feel more comfortable. Also, be sure to stay hydrated. Finally and I think most important, is to pay attention to how you're feeling. I hope this helps. Good luck!!
