Cause and treatment please
Any protruction outside the body (e.g boil )is as a result of urinary tract infection .go for proper diagnosis like urine m/c/s and fbc.
That’s boil,in case of other time I’ll advice you to use local treatment first,once you have detected it just plucks out some dirt in your hear and put it on it do it at least three times in a week
Mosquito bites or other insects
