Causes and treatment of a lump on inner thigh

A lump on the inner side of your thighs could be hard or soft, itchy or not itchy, painful or painless depending on the causes. Let us explore some of the common causes.

1. Ingrown hair cyst and treatment

A painful bump can be caused by an ingrown hair in between your thigh. An ingrown hair is the curling of hair back into the skin instead of outwards. This lead to the development of painful pus-filled cyst in the inner thigh near the groin in both females and males should it be infected. An ingrown hair cyst pus maybe greenish or yellowish in color.

These bumps cause irritation and discomfort. The condition may worsen if the cyst is infected with bacteria. An infected cyst may lead to the development of a boil in this area which is an entirely different type of problem.

Treatment for Ingrown Hair Cysts

  • A warm compress will increase the blood circulation and reduce the inflammation of the cysts. Soak a cloth in warm water, squeeze out the excess water and press it over the cyst. This will also provide a soothing effect.
  • There are also over the counter steroid creams that usually reduce inflammation and irritation of the cysts.
  • You should avoid re-using shavers to prevent ingrown hair. Also, adopt the right shaving techniques or try other hair removal techniques, including permanent hair removal. 

2. Infections and boils 

Painful itchy small red lump on the upper thigh is a sign of a bacterial infection. With time the bumps will be filled with pus to form boils. Infection of the hair follicles can also cause boils on your inner thighs. Bacteria can accumulate due to sweating, which may encourage infections. Similarly, thighs rubbing against each other can encourage these infections.

In case of a boil, within a few days, the boil will break-open and drain out pus. You may get a scab and scar on inner thigh if this happens. This may also spread the infection to other parts of the skin leading to recurring boils that may be very difficult to treat. Symptoms such as fatigue and fever may be reported by a patient in case of a serious infection.

Treatment for Boil and infections 

  • Applying a warm compress can help treat the boil at home. To do this, you soak a clean cloth in warm water, squeeze out the excess water and then press the cloth on your boil. It is recommended that you do this at least 3 times a day until the boil drains and heals.
  • A warm sitz bath can also help reduce the inflammation.
  • Large boils may need to be drained by a doctor or a surgeon. Your doctor may also prescribe some antibiotics to treat bacterial infection and painkillers in case they are so painful.

3. Genital warts and treatments

Itchy bumps on the inner thigh in females or male could be a symptom of genital warts. On prevalence, there is what statistics state: 

About 1 in 6 Americans (16.2%) aged 14 to 49 is infected with HSV-2. HSV-2 prevalence was nearly twice as high among women (20.9%) than men (11.5%) – Wikipedia 

Though it mostly affects women, men can also get warts. Warts are itchy, small blood-filled bumps and may appear in clusters. Apart from this area, genital warts can grow on the vulva, vagina and the anal canal.

The HPV Virus is transmitted through having sex with an infected person. The virus has been closely associated with various types of cancer.

Treatment for genital warts

  • There is no known cure for the HPV virus though there exists a vaccine which can protect against the virus and prevent genital warts.
  • Using a condom every time you have sex can significantly reduce the chances of contracting genital warts.

4. Jock itch

Jock itch is the main cause of blisters and inner thigh rash. Jock itch is a fungal infection caused by fungi known as a dermatophyte. The condition causes a red blister on the inner thighs around the groin area and buttocks.

It is mainly caused by lengthy exposure to moisture. This can be because of wearing sweat-soaked clothes for a long time. The condition is also highly contagious; you may get it through contact with an infected person.

5. Inner thigh chafing

  • You should loose wear cotton undergarments that will wick the moisture in your groin area. Sweat contains salt which aggravates chafing.
  • You can also apply talcum powder to absorb the sweat before going out for a run or exercises. BodyGlide is also a good anti-chafing product.

6. Hemangiomas

  • Most of these lumps do not require any kind of treatment because they are not harmful. Though, surgery may be performed if the tumor is interfering with your sexual life. Your gynecologist may also recommend surgery if they find that the lump is close to the opening of the vagina and may interfere with childbirth.
