Also what kind of compensation could I expect, if any?

I'm at 40% - part of which is from a wrist injury and the other a knee injury. My wrist is in constant discomfort and sometimes I'll be using something like a screwdriver, hammer, wrench or any sort of tool that requires grip and I'll agitate it to the point where I'm in pain and lose a lot of grip strength. It also gets a bit aggravated when I type a lot, which I actually have to do for my job. I may need to find a new career field and I know that a lot of manual labor would be out of the question.

My knee isn't as bad as my wrist but now I have consistent pain in another part of my leg which I'm assuming is from my initial knee injury.

I also put in for sleep apnea because it feels like I have less energy than I should. I'm fine in the morning but middle of the day I need to relax and usually take a quick nap. Even after a nap sometimes I don't feel 100%. I did get tested for this before I got out about 9 year ago and they said I didn't have it. Maybe something else that contributes to consistent fatigue?

Anyways I guess I just wanted to ask about people with similar issues that received an increase. Thanks.
