What kinds of things is the PT doing for you , or having you do?
What is your avg pain level?

You don't have frozen shoulder do you? If not, try to keep it moving gently so it doesn't freeze up - that is a whole other bag of problems.

I found this pain scale that describes the levels nicely

[Mankoski Pain Scale

Andrea Mankoski devised this pain scale to help describe the subjective experience of pain in more concrete terms to her doctors and family. Please feel free to use it and distribute it with attribution.

0 - Pain Free
1 - Very minor annoyance - occasional minor twinges. No medication needed.
2 - Minor Annoyance - occasional strong twinges. No medication needed.
3 - Annoying enough to be distracting. Mild painkillers take care of it. (Aspirin, Ibuprofen.)
4 - Can be ignored if you are really involved in your work, but still distracting. Mild painkillers remove pain for 3-4 hours.
5 - Can't be ignored for more than 30 minutes. Mild painkillers ameliorate pain for 3-4 hours.
6 - Can't be ignored for any length of time, but you can still go to work and participate in social activities. Stronger painkillers (Codeine, narcotics) reduce pain for 3-4 hours.
7 - Makes it difficult to concentrate, interferes with sleep. You can still function with effort. Stronger painkillers are only partially effective.
8 - Physical activity severely limited. You can read and converse with effort. Nausea and dizziness set in as factors of pain.
9 - Unable to speak. Crying out or moaning uncontrollably - near delirium.
10 - Unconscious. Pain makes you pass out. ]

If you are in pain and having very bothersome symptoms, I really feel that there should be NO strengthening/building up PT work at all.

The focus should be on pain reliving therapies using ultrasound, massage, manual trigger point work, IF stim and/or even some low level laser.
Passive posture work is good also.

If they aren't doing any of these at all for you, I wonder how experienced they are with this sort of syndrome.

I was in the work comp system and had to go thru many PTs and places before finding really good ones, also my chiro was very good with all those PT type modalities- plus the adjustments helped too..I didn't find him until a year into it.

Due to the work comp "rules/red tape" and having to work light duty for a few months (PT could not offset the driving and trying to work & do ADLs at home) it took about 3 months for the acute pain to resolve, at 5 month mark to see some measurable relief with very light uses and about 2.5 yrs for normal activities to not set off symptoms. As best as I can recall anyway, mine started in 03, so it's been awhile ago.
