I would like to know some more details of your problem to understand better and opine specifically.

Since when do you have those lesions ?
Do you see any scaly or powdery substances on scratching ?
Are you on any medications for other illnesses ?

Hi ,

Thanks for writing back.

Based on your description the lesions could be due an allergic reaction, commonly presented in an insect bite.Such rashes do not last more than a day or two .Taking benadryl is the best option. Also do apply calamine lotion on the affected areas, this will reduce the itch and also prevent any marks after the disappearance of the rashes.

Hope I answered your query.

Wish you good health.
