Didn't have a firm dx from a doctor, did have a dx from my chiro & another PT guy that did the eval for the physiatrist that I saw a few times.
Physiatrist didn't dx TOS he would only call it "chronic cervico/thoracic strain with arm pain"
But his PT that actually did the eval did feel it was TOS but I guess the Dr didn't want to change his written dx.
I was hoping for a firm dx on paper to take to my wc hearing. I'm doing OK as long as I pay attention.
My PCP dr would only call it chronic soft tissue damage.

When I went to see Bud, I made the appt for a full evaluation and asked if he thought it might be TOS due to my repeated RSI injuries in the short time frame.
I did fill out forms with previous injuries and symptoms etc so he had that info too.
He also studied ergonomics and is a ergo consultant for businesses I believe.

He did the checks to rule in/out c spine injuries/causes Traction/compression /angles etc - same as chiro did and the other PT at physiatrist place.

He did find that my top ribs were raised and stuck up in that position- that was causing more compression with collar bone and things in between the two.
He dropped the top ribs down and wow I could drive home with no arm problems.
he alos gave me the best passive posture /stretch ideas I have it posted on my profile album - just click my username and go to my profile to see them.
