Last night I started getting sharp, shooting pains on my TOS side neck and shoulder and up into my lower jaw. Woke up this morning and had a few episodes of the same pain. I have never felt this before. My main pain symptoms have been scalene muscle soreness and the burning, aching in my left arm. And my scalenes have not hurt since I had Botox a few months ago and Tramadol keeps my arm from aching. Has anyone else experienced sharp, shooting pain? I did go to PT yesterday and I stretched my scalene and had the TENS on the base of my neck and around my clavicle. I find it frustrating that I have to speculate if every pain/sensation I feel on my left side is TOS related.
