I've sprained my wrists several times in the past, and I recently found out that for the last few years I have had TMS in my wrists on and off. Today my son was waving his arm around and he accidentally pushed my hand into a bent position a little farther than I would normally have stretched it. I know that can cause a sprain, although he didn't do it with tremendous force. The problem is, I was already having TMS pain, so I'm supposed to tell myself that my wrist pains are TMS. So how do I know if it's still TMS or if the increased pain is because of a new sprain that has to be rested for the next month or so?
