Chroma, I have been suffering and doctoring for TOS for many years. First on the left side and now the right. The right side is worse because the TOS is arterial and causes me a lot of pain, swelling and fear. Due to past surgical complications I am not eager to go for surgery yet. I now see a vascular surgeon who says it is only a matter of time before I will end up in surgery (we will see).

I wanted to paste this little portion of Dr. Ellis Wladislaw's website which you might want to look at. I have used several of his recommendations and they have helped a little. Anyway this section was found under the Treatment tab:

..."Pharmaceuticals, unfortunately, are of minimal-to-moderate help. When appropriate, diazepam (more so than its congeners) helps in reducing the irritability and attendant trapezial and scalene muscle spasm. Other muscle relaxants, such as Flexoril or Soma, can be of benefit as well. Opiates are usually of minimal benefit and have obvious problems in select individuals. Antiepileptics and vasoactive agents play an even lesser role but can often be effective, again in select individuals."

Diazepam is the only med that has given be a little bit of relief at times. It was interesting to read it has helped you as well.
