Thank you, Jomar!

I will certainly go through the threads you linked. I have tried trigger point injections with the doctor before, but the relief was temporary. What could be much more beneficial (besides Botox maybe, which I am still trying to look into) might be so-called myofascial release... if it's possible to release muscles as tight and painful as my upper trapezius and scalenes. It couldn't hurt to have a good DO or PT work on it (if I can find one). My sports medicine doctor also mentioned dry needling as a way to work on trigger points, or just using a theracain.

I have the theracain and haven't been able to make a dent in it, which makes me suspect it's TOS and not just a trigger point. I think where I'm going with this is that I'll probably need to look into a combination of PT and more advanced treatments for TOS like Botox....
