I have a very strange problem - one that I haven't been able to find any info on either. Some of the tendons on the back of both of my hands have been displaced.
A little over a year ago, I was playing badminton in gym class. I unknowingly held the racket wrong, and continued to play. Halfway through, I had severe pain around the knuckle of my ring finger. It later on subsided.
Ever since then, the tendon (on the back of my hand) for my little finger has been displaced. It shoves over about 1 cm down from the knuckle, and from there on it is colliding with the tendon for my ring finger. Now, my ring finger is being pushed against my middle finger. This is for both of my hands!
For a while, aside from the displacement, it was fine. A few months ago though, when I typed, moused, or wrote too much, I got pain in my forearms (back and front) and both of my hands. I've tried to stay away from the computer, and use better quality keyboards, but nothing works. Now, I get pain when I'm not using the computer, and for fear of damaging my hands even more I've tried to stay away from the computer.
Also, my grip strength is shot - it's so bad. My ring finger and little finger have little to no strenght. It hurts if I try to hold something to tight, or apply force to anything. Sometimes, I can't even open a new water bottle.
In addition, I have bits of numbness in my fingers (the sides) and parts of my hands. I went to see a nerve specialist, and they found nothing. It has been getting worse and worse, and I have no clue what to do. Does anyone know what is going on, and possibly how to solve it?
