Three days ago in the middle of the night I woke up throwing up. That progressed to terrible bowel movements and a rash that looks like hives all over my face, some of my neck and some of my chest . Then I had an episode of my entire mouth going numb, not tingly, just plan numb... that lasted about 30 minutes. Since then , while taking Benadryl 3-4 times a day I have had a few instances of numbness and one time with my index and middle finger have shooting pains on my right side. My hives haven't gotten any better yet. Any ideas on what this could be? I have talked to many people and so far the majority says stress. But for some reason I think it's something else. Thank you in advance!

Sounds like its an allergic reaction to something you have ate.
I get the same thing in my mouth when I eat certain Chinese food. Have you had this before? Ate anything you haven't before?

You need to see a doctor. We can't diagnose this online but you need to take care of yourself and seeing a doctor now to be sure it isn't anything major is the way to handle it.

You need to see a Physician - numbness and tingling are nothing to fool around with. It could be anything or nothing.

The rash might or might not be related to the other problems.

Please - see a Doctor.
