What causes a raised area around the depressed area due to a bite?
Patient: i have a single bite (i think its an insect bite), on the top of my foot....about 1/2 inch in diameter... i see what looks like a single puncture mark, sitting on a raised area, surrounded by an annular depressed area, which is finally surrounded by an annular raised area.... Doctor: Hi,It seems that there might be having some local allergic reaction after insect bite.Take Benadryl or Cetrizine for 2-3 days.Apply Caladryl lotion on affected part.Ok and take care.
