How do I get rid of severe. Jock itch?

OTC vs RX. The questions is...Over the counter or precripton. Over the counter products are fairly good - creams, powders, and sprays. However, they sometimes do not kill the specific fungus. If 2 weeks of use does not clear it up, try a different product. Still not working....Get a prescription. Also, keeping the area clean, dry, and cool as possible is essential.
