I was bitten yesterday on ankle and it liked the average mosquito bite. now the red area has tripled in size, hot and throbbing. it also hard on area?

Antibiotic: This bite has an allergic reaction, bacterial cellulitis, and possibly a blood clot under the skin. Antihistamines and antibiotic treatment seems needed. Go to the. Hospital emergency room if your physician can't examine you tonight.

Hot and throbs: Heat, throbbing and swelling of an area means inflammation, which could be from infection (cellulitis), the direct effect of toxin from the insect or vigorous allergic reaction to insect protein. In any case, good reason to seek help, because it might get worse.
