Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itchy, red and slightly raised rash over the inner thigh can be due to a few causes like
Contact Dermatitis caused due to irritation or
allergic reaction with certain Detergents, cosmetics, soaps etc..
It can also be due to
fungal infection causing Tinea Cruris..
I would suggest you to first of all keep the area dry, clean and free from moisture..
You can apply antifungal creams like Clotrimazole, Terbinafine etc for reducing infection..
In case if it does not resolve in two weeks an
Oral antifungal therapy like
Griseofulvin, Terbinafine or Fluconazole can be advised..
In addition to it wear loose fitting clothing, cotton undergarments and avoid moisture or humidity in that area..
Hope this information helps..
Thanks and regards.
