Itching problem. Provide me solutions!

There isn't enough information to give you a specific diagnosis. If the thighs are dark and the groin region is also dark associated with itching, its likely that you may have Tinea versicolor. You may require antifungal tablets and a topical antifungal cream. These following steps may help: - Avoid using oily skin products - Reduce your exposure to the sun. Exposure to sun may trigger or worsen an episode and a tan makes the rash more visible. - Do not wear tight clothing. - Change undergarments regularly - Wear breathable fabrics such as cotton to decrease the sweating. - Keep areas where there is sweat accumulation dry regularly and apply powder in those areas to reduce the moisture. If the problem is persistent I would advise you to meet a dermatologist.
