The restrictions are a real problem for employer & Dr to figure out.
I ended up walking the parking lot at work as "security" - my restriction at that time was "no hands use" -since previously my dr had wrote "no repetitive hand arm use" and HR person in charge had me sorting papers & putting in 4" binders that were over stuffed already -
repetitive to the max -IMO
anyway I didn't last at that very long - 1 day and I was hurting as bad as if at regular job duties.

The goofy thing was that I still had to drive 20 miles to get to work.

Dr tried to write out workable limits but in an assembly job not much is non repetitive .. we tried a few other departments but scanning & entering large blueprints into computer system was hand /arm intensive, QA - testing same thing...

About the only thing I could do long term was receptionist , but sitting at the front desk 4 hrs was about all I could handle - sometimes it was boring as all get out & sometimes it was crazy busy.
We did have a head set w/mic for the phone and did not have to hold the handset at all.

Do you have any obvious cause showing on MRI or Xray?

Do you have more of the vascular or nerve type TOS, did the dr say anything about that?

Any trigger point work?
Sharon Butler style stretches?

PT during the time I was still working did not do much at all to help, it was only after I was off work that we started to make headway.

And I also focused on reading everything I could find about RSI and then TOS and then explored therapies, posture/bodywork & alternative care.

We have some polls on symptoms & surgery & therapies.
