It sounds like the nerve got aggravated it should have calmed down a bit by now tho and your description of pain issues fit t.n. ( not the feeling sick to tum thats usually med side affect)
can i ask if the area is warm or hot to the touch dose it turn red?? if so thats more r.s.d.
dont panic you will be okay once you see the neuro they can rule out things and will know if it is t.n. or another type or neuo-pathic pain and then start you on the proper meds.
when is your apt with the neuro doc?I hope it goes well and you get some option for pain relief. Please let us know how things go . and remeber we are here for you.
PEACE
