thanks for posting your query.
i can understand your concern.
these bumps could be mosquito bites, the condition is called prurigo mitis
. its a delayed reaction a bite that ay have happened earlier.
these bumps need to be treated with a mild steroid
cream like hydrocortisone
, to be applied twice a day for 5 days.
you need to use a mosquito repellant daily in order to prevent these bites from happening.
