Your symptoms are suggestive of tinea versicolor. Tinea versicolor is a fungal infection of the skin. It's also called pityriasis versicolor and is caused by a type of yeast that naturally lives on your skin. When the yeast grows out of control, the skin disease, which appears as a rash, is the result. You will require an antifungal tablet, antihistamine and antifungal topical 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.
