Just wanted to drop by and welcome you to this wonderful forum.
I'm very sorry to hear of your battle!
You pose some very good questions and I see you've already found the forum specific to RSI......

Another good way to target posts pertaining to your questions is to use the 'search' feature at the top of the page and type in key words......
regarding your employment questions, or the RSI, medications.......
There's so many places to look here at NT......I wish I could give better input....but for now just let me give you a and let you know that there are many here who care.
You'll get feedback shortly

Best Wishes
Rae
