Thanks Anne.

I don't have cervical ribs, just a very narrow thoracic cavity. And, yes, most of the females in my family have the narrowness, and my mom has a few little TOS symtpoms from time to time, but nobody in the family has actual TOS like I do.

Interesting about the breathing -- I have such a hard time, especially in the last couple of years, with breathing. In fact, today, before I read your post, I was having some trouble and I had the thought, "How much worse will this be if I get pregnant?" Funny you should then mention it. Anyway - Another thing to discuss with the doctor.

I appreciate any response I get - Everything gets you thinking. I'm glad to hear you think I'll be okay, and that your symptoms did subside.
