Is there a local cure for jock itch?

I have had jock itch for several years . It comes and goes, I have used nearly every conceiveable over the counter drug. I now have it under my arms. It smells and is very embarassing . I need help urgently., medical opinion claims there is no cure. I doubt it.

Consult with an ID, an infectious disease medical practitioner. You may not have the bug you think you do, or, you may have a highly resistant strain. As an RN, I HIGHLY recommend this. You shouldn't have to suffer with this. I hate bugs.

I don't know about local but if you put anti fungal powder and apply it 3 times daily after washing with soap and water and patting dry for 14 days. Don't stop when it gets better continue for entire 14 days and make sure you clean area before applying more powder. If this doesn't work it may be because the fungus has acquired an immunity to over the counter products because you have to continue treatment even after symptoms subside and then you should let your doctor know and see if he will give oral anti fungal med like diflucan. If he won't help ask for referral to dermatologist.
