Okay...again this is all just my opinion based on the stuff I have seen and had to deal with...but if I were you I would not ask to be taken off work. Get a note from the doctor releasing you to work and if you feel you can do your job without restrictions then don't ask for any.

I understand your worries about keeping your job and about them finding some other way to get rid of you. So...here's the thing with that. There is no way to control what a company will do. But you can do your best to protect yourself and advocate for your rights. Companies do know the laws, so you need to know them too. Documentation is the single most important thing you can do if you feel that you are being discriminated against because of your disability. Make notes of the date and time of the conversation, what was said, and if there were any witnesses to the discussion or comments. Report your concerns to HR and follow the company procedure for reporting claims of harassment. They have to follow up on them. If the problems continue, then file a compaint with the EEOC/ADA or consult with an attorney.

But I would hold off on any of that until after you see the doctor and get the release to work. At this point they may just drop it all, especially if there is no decline in your work. Also document your performance any way you can. I know that for me when I was working and was getting a hard time, I kept records of the sales numbers in my area, how they compared to the rest of the district, and awards or recognition I got, etc. They still tried to give me a bad review...but I had all my numbers to back me up and I made sure that I got all that information documented in my self-review.

They may just be trying to take advantage because they think they can. If you just take it all in, act professionally, and continue to do your job well then hopefully they will just stop what they are doing. If not, report the concerns to HR. You are legally protected from retaliation as well as discrimination for your disability.

As far as WC goes...if you believe your injury is the result of (or was made worse from) a repetitive trauma work injury then by all means get advice from a WC attorney and see if a WC claim can be filed. You would need to have a doctor that could back up the claim that repetitive motions either cause or made your injury worse. But WC gets very complicated and can also get very nasty, so unless you and/or your doctor strongly believe that the work activities are responsible for your condition...I wouldn't want to get involved in all that mess. But that's just me and I am sure others may have very different opinions. WC is a nightmare (generally...not always) and you likely don't want or need that stress. Since you are honestly unsure about how your RSD started...I would avoid the whole thing.
