I think I've got a small ganglion cyst on my wrist, which I can feel pressing on a nerve. It's an irritating little bugger. I read one way to get rid of them is to hit them with a big book. It makes them burst.
I tried that on myself last week. Even though I've got some big books--let me recommend the New Oxford Companion to Law in which I've written an entry on globalization and law and it runs to over 1300 pages--I couldn't swing it hard enough other than to cause me to jump out of my chair screaming blue murder.
So I enlisted the help of a friend who is very strong. He's a personal trainer. We put a cushion under my wrist and he hoisted my copy of the complete works of Edgar Allan Poe (prolific writer) over me.
"Turn away and take a deep breath," he said. Wham! God, it hurt.
It was still there. "Let's do it again," I suggested. Wham!! Missed the ganglion but hit the rest of me.
"Last try," I said. Wham!!! The hardest yet! "Shit!" I heard. My friend had hit both me and himself and was now bleeding profusely.
My wrist was numb and vaguely blue. I couldn't tell if the ganglion had burst or not. Sometimes I think it's OK, others it's the same as before.
I can't type very well today. And my friend took away several of my band aids for his injury.
Maybe there's a reason to leave it to the specialists. Wikepedia no longer recommends this way.
