I have also had trouble with a ganglion cyst.I have had it on and off since high school, it would "pop" and then come back from time to time. A couple of years ago it came back and somehow trapped a nerve. It was really painful and made my fingers numb so I had it surgically removed. I was the lucky one who had it come back about 2 months ago and I had to have it surgically removed again! Dr. said it most likely won't come back again, but he said that the first time. I have a nasty scar on the top of my wrist, but it's better than the pain and numbness. When those girls had them drained I knew it would be back within days, it's a sac in there that fills up, you have to get rid of the sac to get rid of the cyst.
