Looks like a fungal infection
of the skin
Thanks for posting on HCM,
I am very pleased to be able to assist you.
From the appearance of the rash
it looks like a fungal skin infection
order wise known as ringworm.
Fungi are germs that can live on the dead tissue of the hair, nails, and outer skin layers. Tinea corporis
is caused by mold-like fungi called dermatophytes.
Fungi do well in warm, moist areas. A tinea infection is more likely if you:
- Have wet skin for a long time (such as from sweating)
- Have minor skin and nail injuries
- Do not bathe or wash your hair often
- Come in close contact with other people (such as in sports like wrestling)
Ringworms are often painless and non-itchy such as in your case.
In order to confirm or rule this out, your health care provider maybe able to conduct an examination by scrapping skin from the rash, then testing with potassium hydroxide (which will indicate positive if indeed fungi but negative if not).
If I am correct, then you should be able to apply OTC antifungi such as miconazole
or ketokonazole cream and within a couple of days to weeks you should get rid of the rash.
However, if the rash is due to another underlying condition (early signs), then you will require further medical investigation to determine the actual onset of the rash. As red circular flat rashes have many differentials but the most common is tinea corporis.
Hope this helps and wish you the best. If you have any further concerns, please feel free to write back.
