I fell into a door 4 days ago and I have had pain in the top of my wrist, I went to and Urgent Care center and they took an xray, it did not show any fractures, they said i probably streched the ligaments. The xray showed a small cyst on the bone area. I freaked out and first thing I thought was cancer. What could this be. I had carpel tunnel surgery on the wrist a little over a year ago.
