I had a ganglion cyst years ago, I took large dose daily of crystal "C". The pain stopped first, then the bump disappeared. A few years later, I was pressured to stop my "C" intake by my GYN, because I was pregnant... Mistake. The ganglion cyst returned, but disappeared after I started by crystal "C" again. Crystal "C" is a high dosage vitamin C. My daughter is now 18 years old, and the cyst has not returned.
