Hello,
For jock itch,wash your groin daily and then dry thoroughly by pat drying,not rubbing. Keep your groin area dry and keep a separate towel for yourself. Most forms of jock itch respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine, and clotrimazole.
You can consult a pharmacist and get any cream or lotion containing these ingredients. Some of them are Lamisil, Monistat derm, Mycelex, and Nizoral.
In case the symptoms persist then pls consult a dermatologist in that case.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
Local application of clotrimazole powder may be an option.
