I know you can't type a lot... I don't know what things PT is doing for you... does DC "only" do adjusting?

Oh if you have a laptop with mic or smart phone , use the voice dictation to "write" your post.

But if the PT & the DC aren't improving things or lessening your pain.. I'd seek out others that might be more skilled..
Sometime you will find very very good ones, but you may have to try a few before you find the gems.

Poor PT will mess you up more, please be careful.
Do not do anything if it makes you hurt more.
And if you are in high pain, they should only be doing pain relieving things for you.
like ultrasound, stim, heat , massage, passive gentle stretches.

Does the PT or DC address the collarbone at all?
Maybe ask for top rib check/rib mobilisations..

There are injections , I'm not sure which kind of MDs to suggest you look for for those.
Littlepaw suggested pain management or Physical Medicine and Rehabilitation (PM&R) physicians, also known as physiatrists.
Those are a good places to start.
