Re: Itching all over!
My first reaction to itching was also possible drug reaction. May be its possible to fall in the category of allodynia type pain?? No idea on that.
The nerve pain in your face, if unrelated to your jaw, could be coming from the trigemenal nerve. It has a branch across the top, across cheek, and lower closer to jaw level. Sorry I don't know a great deal about it, could be a neuralgia type pain.
