Hi,
I have read your info and can definately see similarity with the way I am presently feeling. I have been having some bezzard symptoms for the past year. Burning sensation over my body, pain anywhere bu only last a second, muscles spasms and other frightening feeling. I have seen many doctors and all my checks came back normal. I too believe it is anxiety and hoping one day the way i feel will be normal again. Hope you are feeling much better.
