Dont know much about it,but once at a gp appointment I mentioned that I had been getting pains in the backs of my hands and he prescribed ibuprofen gel and I bought some stretchy hand supports that look like fingerless mittens and found they really helped.
you need to get a hand brace/support to immobilize it tbh.you dont want it to get any worse between now and seeing your dr.have you had any trauma to your hand.trapped it or maybe banged it on something and forgot?
I had this really bad after DS was born - ended up have both my wrists operated on. While I was waiting for the op I used all the main pain killers and wrist splints at night. The consultant I saw called the splits (don't laugh!!) 'cock up splints' becuase they put your wrist at a 30 degree upward angle. The splints really helped I have to say though they were a pain to wear. I work at a PC most of the day so my employer got occ. health in they suggested a gel wrist rest, making sure that the monitor was aligned correctly and that the mouse was close by so that I didn't streatch for it. They also recommended a vertical mouse which they got for me - it took a few dyas to get used to but once I did it was fantastic - when I use a traditional mouse now it is so uncomfortable. The Occ. health women told me that she would like to see vertical mice used as standard as it would help aliviate a lot of wrist problems but as they are around £60 a shot I think its unlikely my employer (local gov) will ever do that. Hope it gets better soon.
