[a 5 pound lifting limit and hospital discharge instructions with "no heavy lifting, bending, twisting" ]

the main problem with those restrictions is they aren't very specific - nothing about repeated lifting or hours of etc...

my doc always wrote along with lifting and weight restrictions - "no repetitive hand use" or "limited rep hand use"

of course in an assembly situation, well nearly any production/manufacturing type of job, that really limited what I was able to do.
even the very simple light work of prepping the parts for assembly was still hand and finger intensive... so then I was sent to do paperwork type of jobs in the offices and that still was pinch/grip intensive
I did get paid to walk the parking lot for 2 months LOL
security LOL
