Razor bumps
Shaving your bikini line can leave you with small red bumps on your inner thigh and groin. If the razor bumps become infected then they can even develop into large abscesses and boils. Inner thigh boils, pimples, or zits appear either because of an infection in the hair follicles or ingrown hairs blocking follicles and get inflamed and filled with pus.
Sexually transmitted disease (STD)
According to doctors from the Mayo Clinic, STDs can cause small red bumps and blisters close to the location of your groin and around the genitals. These lesions on the groin can be itchy and painful.
Heat rash
Red bumps between your legs could be caused by a heat rash on your inner thigh. Dr. Benjamin Wedro explains that when the skin’s sweat glands become blocked, trapped sweat causes inflammation with tiny blisters. You may have inner thigh bumps caused by a heat rash if you wear tight underwear or clothing.
Jock itch
Jock itch is a fungal infection affecting the groin that causes an itchy rash and bumps. Dr. Gary Cole on MedicineNet says that if the fungal infection gets worse, you may develop pus bumps on your inner thigh that begin to ooze pus. The rash can spread to other areas of your groin and genitals.
Keratosis pilaris
Tiny white bumps on your inner thigh that are painless could be a condition called keratosis pilaris. Doctors from the Mayo Clinic say that these bumps often affect the thighs, upper arms, cheeks, or buttocks. Usually, it isn’t necessary to treat keratosis pilaris.
