Bro I have trained muay thai for a while and got hit about 1000 times hard, soft etc. but I never got a reaction like that. GO SEE A FU%$ING DOCTOR!!!! GO TO ER!!!! DONT WAIT!!!
There are a lot of nerves in the face that react diffrently when hit in certain spots, no one here is qualifid to tell you what's wrong!!! I studied biology in college but I am no doctor. Go to the emergancy room immediately to get a x-ray, catscan etc. check with your gym's insurance talk to the trainer or owner to get the insurance infomation to pay for the hospital bills, they are required to have insurance for this type of situation. GO TO ER ASAP!!!!!!!!!!!!!
