My suggestion would be to see a chiropractor regarding your back, i see one, and they are absolute miracle workers! As for the spitting, I've never heard of such a thing, unless you are trying to say that u have acid reflux? If thats the case, the chiropractor can help that also, sometimes when the back is out it presses on other parts of the body and almost anything can go out of whack.
Good luck to you,

Hi,
I really couldn't begin to guess what's up here nor would I try, but I would encourage you to see your doctor if you haven't already.
Good luck to you...
