Jock itch is the name for a fungal infection that can cause itchiness, burning, scaly skin, and redness. While it's most common around the groin area, it can develop in any area where heat and moisture levels allow the fungus to thrive. It can be caused by sweating, wearing tight clothing, sharing towels, or not properly drying after showering. If these symptoms are affecting your daily routine, count on HSA-eligible Lotrimin products for your antifungal and pain relief needs.
