I have those exact symptoms. Sometimes I think I'm crazy. The Dr. hadn't heard of those symptoms with Hashi's, but I've found otherwise in my research. For the collar bone pain and chest pain, they come and go. I put heat on and try to rest. I'm starting to notice a cycle of the those symptoms returning every few months around my cycle and lasting a week or two. Chart your symptoms to track them yourself and see if you find a pattern. Along with the symptoms you listed, one thing that also really bothers me is foggy brain, but other than that you nailed my most annoying symptoms. I have other more subtle ones, but those are the ones that bother me the most. Hope I was of help.
