Hence, it is important you go to a doctor before jumping to any conclusions. To help you understand the reason behind this, here are the symptoms and causes of the skin disorders which generally cause rash on inner thighs.

Causes of Rash on Inner Thigh

Sweat Rash: A person can get rashes due to profuse sweating, mostly during summers. Also, a person who has fat thighs has more chances of getting sweat rashes. It occurs mostly along the folds of the skin. One can develop rashes in the inner thigh area from a workout involving running and due to poor hygiene as well.

Heat Rash: Due to heat, or heat combined with humidity, a person has a higher chance of getting heat rashes or boils. The possibility of developing thigh rashes in such weather conditions is high due to the increased sweating.

Jock Itch/Fungal Infection: Jock itch (Tinea cruris) is a type of fungal infection of ringworm. The symptoms of jock itch are itching in the thigh skin folds, red or scaly rashes that blister and ooze. The symptoms of jock itch are patches with sharply defined edges. These patches are usually red with normal skin color in the center.

After showering or bathing, dry the groin and thigh area completely. You can use cold water to wash the affected area and make sure you dry it completely.

If you get sweat or heat rashes, you can use talcum powder to prevent aggravating the rash further. Talcum will help dry and soothe the rashes. There are talcum powders available at the supermarket, which contain mint and have extra cooling effect which you can opt for. If you are overweight and keep getting sweat rash, consider going on a healthy diet and workout program.

For skin rash due to fungal infections, use antifungal powders or cream twice in a day, and keep the skin area clean and dry.

Bad Clothing: Clothing made of synthetic material or having tight-fitting elastic that rubs against the skin can give a person rash on the inside of thighs. A person can also develop allergic reactions to dyes or chemicals used in clothing and get such rashes. Children using diapers often develop diaper rash

Wear loose-fitting clothes made out of cotton. At home you can always wear shorts or avoid wearing pants. However, if you are going for long walks, wear denims or pants that are made of thicker material.

Insect Bites: One can get bumps or rash on the inner thigh due to insect bites, like ants, mosquitoes, or bed bugs. The common insect bites go away on their own after a few hours, but if the symptoms become worse, seek medical help. If you get small red bumps on the skin due to tick bites on your legs, it is a skin condition called rocky for which medical treatment is required.

First of all, wash the affected area clean with soap and water and dry it thoroughly. You can reduce the swelling of the rash or bumps by applying ice packs every few hours. You can also use an anti-itch topical cream, and take an OCT antihistamine tablet for further relief.

Shaving: Many a time, shaving the thighs with a razor can give some razor bumps. This might give you red, itchy spots. In case, you have a tendency to develop sweat or heat rash, then it is possible that the razor bumps might develop into a large rash.

If you shave your thighs, then use a thick shaving cream or gel. Then shave the area in the direction of the hair growth. After shaving, wash the area with cold water and apply a good amount of moisturizer.

Cosmetics: A person might get allergies due to certain chemicals present in cosmetics, like lotion or a specific soap, or even in detergent. If you are using some new product after which you have developed the thigh rash, discontinue the use of such a product.

Poison Ivy/Sumac: On contact, poison ivy, poison sumac, or poison oak can give a person skin rashes, leading to severe itching. One can get such a rash when traveling in the wild or even contract it from a pet.

Allergies: Sometimes, a person having a certain food allergy can also develop rash on their inner thigh. But, in case a person is allergic to some specific type of food, the rashes might occur on other skin regions too along with inner thigh. Common food allergens are nuts, avocados, strawberry, milk, and shellfish.

Eczema: This skin condition is also called dermatitis, and the most common type of eczema is atopic dermatitis which is an allergic disorder. Atopic dermatitis results in dry, red, itchy, and swollen skin. You can prevent this condition by avoiding the allergen which triggers the rash.

The best way to prevent an allergic rash is to avoid coming in contact with the substance which triggers it. However, certain anti-allergy creams and OTC drugs like antihistamines can be used to reduce the intensity of the allergy.

Shingles: In shingles, a person experiences pain, itching, and burning sensation in a body part. Later, the person develops red bumps or rashes on a skin region. If you experience such symptoms, you need to visit a doctor for the treatment.

STD: Sexually Transmitted Diseases like herpes, syphilis, or warts; can cause inner thigh rash in men or women. The symptoms of these diseases differ, but they mostly occur in or around the genital areas, and can spread to areas below the groin, like inner thigh, so one should seek immediate medical care in such cases.

If you observe an inner thigh rash with skin abnormalities in or around your genital area, seek immediate medical help.
