In my family it is common to get them around your tail bone. Ick!

I had one once (10 years ago at the age of *gasp* 30) atop one of the tendons along my lower (is that anterior or posterior...?), right wrist. It wasn't that the cyst was painful; rather, it was annoying in that I couldn't count on the wrist working appropriately. Eventually, the cyst was absorbed and disappeared. That took... maybe six months (?) from when I realized something wasn't right.

Interestingly, though, ganglion cysts are sometimes called Bible cysts because (believe it or not) the recommended treatment in the “Days of Old” was to take a heavy book (e.g., the Good Book) and smash it down atop the cyst in an attempt to break it up. I don’t think this treatment remains the recommended course of action, although I could think of some other “ailments” on which this treatment could be used - effectively even! I remembered the doctor mentioning the alternate name, and told her that I thought she was joking - but it’s true.

Hey my friend had one of these. The doctor said that one treatment was the "heavy book" described above. He was too skeptical to do that and left it alone until by accident one day he smashed his hand against something and the cyst totally disappeared! Do the book trick, it really works. I wouldn't have believed it if I didn't see it happen.

What more is needed! Four out of five Bible Thumpers recommend it! The fifth one, just like the chewing gum commercial, was whacked (inadvertently, of course) in the head by the Bible...

Fall, two years ago, i had the pleasure of getting the super rare-on your neck ganglion (or so they said). Very strange pea-shaped thing about an inch and a half from my cervical vertebrae. It was infected, sitting on a nerve, and I had to have spinal x-rays to insure it was not attached to the bone, which would have meant some sort of bone cancer. It went away after antibiotics and pain killers, no need for surgery. i dont know if it was ever actually a ganglion, the surgeon i had to see was skeptical. However, that was my diagnosis.
