Rash on Inner Thighs

Inner Thigh Rash Causes

Inner thigh rashes due to contact

If the portion of thighs has been exposed to something irritating and allergic, the rash may happen as response. Contact dermatitis or skin inflammation is due to adverse reaction to something that is allergic to your skin. This may include chemicals used in bathing soap, shower gel or detergent (used to wash the undergarments). It can also happen due to thighs rubbing each other, which is quite common in a person with fatty thighs. The rubbing of skins of inner thighs result in irritation (called intertrigo) that causes redness and inflammation of the skin.

The rash on inner thighs may also happen due to contact with poisonous component found in herbs like poison oak or ivy, or present in the insect’s sting or animal’s bite. For instance, tick’s bite can cause Lyme disease that first forms a round shaped wound and then turns into rashes. Disease like Rocky Mountain spotted fever can also cause rashes on arms and inner thighs (legs).

Allergy as the major factor to cause inner thigh rashes

Allergic food and/or medication can substantially cause rashes on inner thighs along with other sites of the body.

In such cases, profuse sweating, vomiting, and difficulty in breathing are common symptoms.

Inner thigh rashes due to cycling first appear as a hot spot in one of the thighs. The burning at this site of thigh is the best indication for stopping it right there.

This may turn into abscess and seek strict surgical attention.
