Thanks for posting your query.
It is important to check if you have fungal infection
like tinea cruris. This appears like raised reddished-brown patches with scaly edges.
This can be treated with some over the counter antifungal creams like clotrimazole
preparations. It is important not to scratch as this might lead to ulcers.
If there is no infection then it could be due to allergic dermatitis
, contact dermatitis
, eczema. You can try the following measures. Keep the groin area clean and dry. Use loosefitting cotton underclothes.
Apply emollients like vaseline and incase of severe itching
you can try oral antihistamines. But this is a prescription medicine and you can ask you medical practitioner to prescribe them for you.
Hope you get better soon
