I had a problem keeping my toungue be normal, but I will move my tongue to my top jaw after I had jaw suregy in August 17,2011.

Can spiting up dry blood damage my jaw after jaw surgery?

I can see why you would have to expectorate blood, but it wouldn't be dry, being in your throat and mouth. I don't think moving your tongue would damage anything. You have to move your tongue. What were your doctor's instructions?

But why do I think I am spiting up dry blood?
