Dysautonomia is an autoimmune disorder. Most doctors aren't familiar enough with it to recognize it or treat it. My doctor cured herself. It requires sticking to an anti-inflammatory diet. If you check it on Google you can learn more about it. Good luck.

My condition is dysautonomia. A hard to diagnose condition. Not really curable although my doctor cured herself but she has strictly stayed on an anti- inflammatory diet which is the key. Compression socks are recommended. There are several nasty symptoms.
