Thanks for your response, and I am so sorry to hear about your friend.

Interesting you mention your stomach issues are caused by spinal issues, I have wondered the same. Seems I have flare-ups w/stomach issues, then horrible upper back/chest/neck/head symptoms. I am sure if anything gets inflamed it is pushing on nerves.

New to this website/forum - found while looking for symptoms similar to mine.

Can TOS cause pains in the chest area, sometimes neck/collarbone/shoulder, too?

Thanks.
