Hey, im experiencing the exact same thing right now. Im kind of worried about it because I cant do push ups with them really hurting. The area I get the pain is if my hand was laying palms down its on the top of my wrist on the inside, below my thumb tendonds in the wrist joint. I have a feeling it may be tendonitis. Im going to see my doctor on monday to see what the deal is. I researched it a little on the internet, what causes it is your carpel tunnell is to tight around your tendons causing chaffing or rubbing of the two and apparently you can get surgery for it, but seeing as I have BMQ in three weeks, I dont think thats an option. Secondly you can get a shot of cortozone in your wrists, apparently this relieves pain in the affected area for up to 3 months. However I have heard some things about negative long term effects, anyone know of these for sure?
Either way I would take it easy on your wrists as I have been doing, and if you would like to continue doing pushups, dont lay on your palms but instead make a fist. works if your on mat or something. and it even works your arms harder I find.
