A lump, bulge, or swelling in the groin most commonly occurs after an
injury. Sometimes the injury is so minor you do not notice it at the time. Home
treatment usually will relieve symptoms.
An infection can cause
lymph nodes to swell. Infection in the leg or foot as
well as in the testicles, penis, or scrotum may cause lymph node swelling in
the groin. If the infection is minor, the swelling may last a few days and go
away on its own. When an infection is more serious, lymph nodes may be warm and
tender to the touch. Redness may develop and the swelling may increase. When
there are signs of infection, it is important to find out what is causing the
infection. Lymph nodes may stay enlarged for up to 4 weeks after an infection.
This is normal and not serious.
Certain diseases may increase your risk of a serious infection.
People with
diabetes,
peripheral arterial disease, or an impaired
immune system may require medical treatment at the
first signs of infection.
An
inguinal hernia is a bulge of soft tissue through a
weak spot in the abdominal wall in the groin area. An inguinal hernia may need
surgical treatment.
