Last night my boyfriend bit my neck during sex -pretty hard, but no blood/teethmarks/bruising or anything like that- and immediately pain shot up from my neck to my left ear. Immediately, my entire outer ear felt painfully tingly and sort of numb. By the next morning it was no longer painful, but it felt a bit like how your mouth feels from dentist's anesthesia, weirdly desensitized.
It has now been an entire day, it's still numb, and I'm starting to get worried. What causes this? Is it dangerous? Will it go away?
