Got badly stung by a nettle yesterday on the finger. There was no raised rash or weals, but my finger is still numb nearly 24 hours later and I am starting to worry about it. Bad pins and needles sensation, fizzy buzzing feeling in top third of finger. Googled and think it may be a trapped nettle hair irritating the nerve? How do I deal with this - will it resolve by itself? There is a little red dot but nothing else.
