I forgot to ask on the TOS side- have you had any c spine xrays or MRI to check for c spine causes. {damage to the nerves at that point}
It's very important to get that verified as a yes or no for the c spine /nerve question.
frogga is right, deep proper breathing {diaphragmatic}can really help to relax and de-stress. When we get all tensed up we tighten our whole body up {muscles} and will take smaller shallow breaths-
we need that oxygen getting to our cells

I know it's scary for you now, but there is always hope that some good help, remission or even someday a cure will be found.
And if it is TOS also, we just had a thread about Self Help Remedies
