Welcome to Healthcare Magic Forum
You seem to have developed a fungal infection
of the groin region..Which can be either tinea infection or candidiasis
You should try to keep the groin region clean and dry
Do not apply any kind of oils or moisturizing creams over the groin region
Wear cotton undergarments inorder to reduce sweating.
Now as you have been using Clotrimazole
gel since long, You can now switch over to another agent like Terbinafine
gel over the affected area twice a day.
Also take oral antifungals like fluconazole
like 150 mg once a week for upto 6 weeks.
And to relieve the itching, take oral antihistamines like levocetrizine once a day .
Hope it helps
