re: Anybody had a ganglion cyst before?

They are also known as "Bible cysts" because the old remedy for them was to whack it with the family bible to release the fluid.

Believe it or not, the one I had on my left wrist was taken care of by my chiropractor. He took my hand and put both thumbs over the cyst. He then asked for me to relax my wrist as he brought it upward and pulled down on it. This drove both of his thumbs into the cyst sharply at the same time. He went on and adjusted me, and by the time I was back out to the car, the fluid was gone and all I had was a sore wrist for a few hours.

That was 8 or so years ago, and it has never come back.
