I was diagnosed recently with POTS and it seems that I get worse everyday. I have the chest pain, headaches, shortness of breath (which is the worst), the intense leg pain/heaviness, extreme fatique, and blood pressure and heart rate that are all over the map. I am guessing I got this from a spell of Mono back two years ago. Who knows! I just know that it seems that there are not many doctors in my area who know about this which is scary. I could live with it if I did not have the extreme leg pain and shortness of breath. If anyone in the Mississippi area knows of a good doctor who could help me, please let me know. It feels like I am spinning my wheels with the doctors. I just want to remotely feel better.
