[ The accommodation was that I would be able to move around to different work stations like the other co-workers. Instead they keep me at the one work station between 10-12 hours (excluding break/meal period). This work station cause the pain to flare up or become worse if already in pain due to the repetitive pressure and stress it placed on my hand/wrist. ]

Reading this part makes me wonder if you might have Thoracic outlet syndrome (TOS) or some related RSIs.
I had the same problem when I was working, I really pushed for rotations & cross training at my work place after I got my first extreme flare of RSI..more so after the accumulated injuries started flaring more often..

Here is our TOS forum & the sticky threads to see if it fits your symptoms.

But unfortunately many GP or primary care MDs are NOT fully up on the condition..
They may say they are- but have biased or incomplete knowledge..

PTs and chiropractors can be helpful especially if they are skilled & have advanced training. There are plenty of self care things you can try too but it does take time and time off work usually.. Usually not a quick fix thing..
