If you are working or still using your hands/arms etc quite a bit it will take even longer to see results.

Sharon Butler explains it with a health bank account analogy -

you are starting out at zero if your pain/symptoms are high.

you go to PT & rest, so you gain say, 100 dollars in your account { I mean good PT - specific for what helps you to feel better}
but if you drive to work and work and drive home you have to deduct 75 from that account - subtract even more $$ if you hurt more than before you went to work...
plus you would subtract $$ for any other uses that you did between PT /resting etc..

this is just a simple version of her analogy

- but it really made sense to me when I was having PT & still working
and why I wasn't gaining much by way of improvement at the time - but of course my doc, wc and employer didn't take that into consideration.... that some will need time the off to see good results with PT.

All I was doing at that time was going to work, PT sessions and then resting at home with ice/heat on my arms and doing the gentle stretches. My dx at the time was basically RSIs. I didn't know much about TOS til later. LOL if I knew then what I know now...
