Rashes on inner thighs appear due to exposure to irritants, allergies and certain diseases.  We shall discuss them one by one:

Irritants or Allergens

When your inner thigh has been exposed to irritants or allergens such as chemicals coming from detergents, shower gel or bath soap, rashes may appear as a response which means that your body has sensed the presence of a foreign substance.  Conditions such as these can be called contact dermatitis or the typical inflammation of the skin.  Exposure to irritants can cause rash on inner thighs due to constant rubbing or friction.  Contact with other poisonous substances like poison ivy and insect bites can also cause the appearance of rash on inner thighs.

Food or Medications

Another major cause for the appearance of rash on inner thighs is allergies to food or medications.  Generally, some food or medications can cause the skin to be irritated or inflamed.  Again, this is the body’s response to the entrance of a foreign matter.  Common foods to watch out for that can cause rashes on other parts of the body including the inner thighs include strawberry, shellfish, peanut, and avocadoes.

Reactions to these allergens are generally controllable.  There are only isolated cases where it becomes fatal.  In instances such as those, a slight exposure can target the heart, kidneys, joints, and even the intestines.  Note that once there are symptoms such as general itchiness, difficulty of breathing, excessive vomiting, and profuse sweating, then it is best to go to the nearest emergency room right away to seek medical treatment.


Apart from exposure to irritants and allergies, another major cause of rash on inner thighs is the presence of diseases, specifically skin diseases such as eczema, impetigo and psoriasis.  All of these can cause skin eruption or produce rashes on various parts of the body not excluding the inner thighs.

Autoimmune diseases or those diseases that cause the body’s own immune system to attack itself also causes rashes.  Sometimes when this is the identified cause, the aim of the treatment is palliative or aiming to promote comfort during the progression of the disease.


You would feel generalized itchiness over the affected area with redness and swelling.  There would also be irritation and inflammation and the presence of a burning sensation.  Pain is sometimes involved especially during severe allergic reaction.  Symptoms occur depending on the cause.  These symptoms are response to foreign substances that have come in contact with your skin.

When the reaction is severe, difficulty of breathing and the presence of blisters over the affected area are common symptoms that you need to watch out for. When these persist, you should go directly to the nearest emergency department and seek prompt medical attention.


There are many remedies to consider when you find yourself afflicted with rash on inner thighs.  You can try natural or homemade remedies and the various medical treatments that are available.

Natural remedies

Here are some common natural remedies that you can try:

You can use vitamin C or fruits that contain ascorbic acid such as lemon and orange (unripe orange is preferred since it contains more vitamin C).  Apply or spread the juice over the affected area for three to four times a day until it becomes dry and until you have observed the disappearance of the rash.  Vitamin C contains antioxidants that dry up the rashes healing them eventually.

Chamomile tea can also be used to wash the affected area.  This infusion can lessen itchiness and reduce the presence of irritation.

Taking an oatmeal bath also relieves the presence of symptoms.  All you need to do is include a cup of uncooked oatmeal in a tub of warm water and soak in it for 20 minutes.  You can do this every day until symptoms subside.

Medical treatment

The use of anti – allergic drugs such as antihistamines or diphenhydramine (Benadryl).  Note that a dermatologist must be consulted first before taking this drug.  Common dosage is 5 mg/ tablet taken until symptoms subside.  Drowsiness is one of the side effects so this is best taken at night.

If diagnosed with eczema, treatment would include the use of corticosteroids in order to relieve inflammation and the presence of itching.  Dermatologists would determine how long this treatment should be because prolonged use can lead to undesirable effects.

Topical creams especially those infused with retinoid or vitamin A is also useful in relieving most symptoms especially when diagnosed with psoriasis but note that this should be applied under the proper guidance of a dermatologist to prevent side effects from occurring.

Another medication worth considering is immunosuppressant drugs especially in severe cases of rash.  It can fade the rash and eventually make the color milder.  Note that these drugs can damage the kidneys and it can also affect blood pressure so caution is required if this is the course of treatment chosen.

Hydration is warranted when you are experiencing any kind of skin condition.  Dermatologists would recommend that you drink 8 to 10 glasses of water daily to keep your skin hydrated.  Moisturizing creams applied to affected areas can also be a remedy. Make sure that the creams used include vitamin D and vitamin A or retinoid.
