Thank you for your query at DoctorSpring.com
From the image attached, it looks like you could be having pityriasis rosea. PR is characterised by oval to round small red rashes with slight scaling at margins. Such lesions are usually preceded by large red scaly rash or rashes known as herald patch. Sometimes there could be a history of fever or preceding sore throat. PR lesions could be itchy. These are usually self limiting and resolve in few weeks.
However to have symptomatic response, one can take oral antiallergic like levocetrizine and apply calamine lotion mixed with steroid lotion.
Other differentials to be considered are tinea/ringworm, lesions of secondary syphilis, seborrheic dermatitis, drug rash.
So please let me know
If these lesions are itchy
if these lesions are typically ring shaped
if you have dandruff in scalp
any history of unprotected intercourse with unknown partner
any genital lesion
history of drug intake
history of herald patch.
Answer these queries and we may take the discussion further.
