Welcome to Healthcare Magic Forum
Firstly, i would like to clear your query that dermatologists are also venereologists ie they deal with all sexually transmitted diseases also..
Now as far as your present problem is concerned, you seem to be having Candidiasis
of the groin region..
First some general precautions:
Wear cotton clothes and undergarments in order to reduce the sweating
Do not apply any kind of oils / moisturizing lotion over the affected area
Now you dont need to apply aloe vera
cream over the affected region.
Just give warm saline compresses over the affected area twice a day and then apply clotrimazole
also , you will need to take oral antifungals in the form of fluconazole
150 mg once weekly for 2 weeks...
In case of severe itching
, take some antihistamine like levocetrizine once a day .
If inspite of the above measures, the lesions continue to persist or increase , then you might have to see a dermatologist for proper assessment and management
Hope it helps
