Hello XXXXXXX

Thanks for posting your query. One thing that is important from the description of your rash is that the rash is not itchy and is swollen and red. Secondly you got it when you played sports. From these symptoms two possibilities are important.

1)     This rash can be due to chafing or friction rub between the thighs with the genitalia or with the skin and the clothes. Chafing is basically skin irritation and redness which occurs when skin rubs against skin or clothing.

2)     Second possibility is of intertrigo skin. It is a skin condition caused by inflammation of the skinfolds aggravated by heat, moisture, maceration, friction, and lack of air circulation and is caused by two skin surfaces rubbing or pressing against each other.

I suggest you to get the diagnosis confirmed from a dermatologist and get a KOH examination of the skin scrapings to rule out any fungal infection and a Wood’s lamp examination to rule out any erythrasma skin which may resemble both the above mentioned possibilities.

Follow these methods for a quick relief from your symptoms:

1)     Wear cotton clothes and underwear and avoid wearing any coarse or synthetic material. When doing exercise wear athletic tights or cycling shorts.
2)     Wear clean and dry clothes and use a mild detergent to wash them. Dried sweat, chemicals, dirt, and other debris may aggravate the condition.
3)     You can apply some calamine lotion at the rash as it will help in soothing the skin.
4)     Application of mild corticosteroid cream and oral antiinflammatories after a prescription from your doctor are helpful in reduction of the redness and inflammation.

Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.

Wishing you good health.
