What is Inner Thigh Rash?

Skin rashes between the legs and close to the groin are known as inner thigh rashes. They include the formation of red bumps, inflammation of the skin, redness, itchiness and a burning sensation. Rashes around this part of the body are common due to the environment of the area. Heat and moisture are favorable for fungal growth and infection. Inner thigh remains covered by undergarments and clothing for most of the time preventing sweat to escape the region. The sweat subsequently dries up and causes rashes. However, these rashes are not illnesses of their own, but they may be effects or symptoms of other diseases.
