Groin Lump Symptoms

The groin, or inguinal region, is the area between the abdomen and the thigh on either side of the pubic bone.

A lump in this area can be concerning as it is often associated with groin lump symptoms such as:

  • Groin pain or discomfort, especially when changing positions
  • A heaviness or dragging sensation in the groin
  • A burning or aching sensation
  • Changes in appearance of the lump during activities such as standing, coughing or straining
  • Tenderness
  • Fever

Make an appointment with your physician if you experience these groin lump symptoms in order to get appropriate treatment and counseling.

Groin Lump Causes Overview

There are various specific structures within the groin region – muscles, nerves, arteries, and ligaments.

  • Muscles. The muscles of the groin are the adductor muscles. These muscles allow you to bring your thighs together and work with other muscles in movements such as bringing the knees to the chest. Furthermore, the muscles of the abdomen also connect in this area.
  • Nerves. The nerve that provides sensation and innervation to the groin area is the obturator nerve. Other nerves such as the femoral and lateral cutaneous also pass through this area but do not give direct sensation to the groin.
  • Lymphatics and underneath the skin there are three to five lymph nodes – structures throughout the body that play an important role in allowing the body to fight off infections.
  • Inguinal ligament. The inguinal ligament is a band of fibrous tissues that helps protect and support the other tissues of the lower extremities. The inguinal ligament forms the bottom of the inguinal canal (a triangle shaped opening in the groin where the spermatic cord (the cord that holds up the testicles) passes from the abdomen to the scrotum.

Conditions that affect these structures can result in lumps in the groin area.

Hernia

A hernia occurs when part of an organ pushes through an opening or weakness in the muscles/tissues that surround it. The protruding organ can result in a noticeable lump or bulge in the area. Hernias in the groin are called inguinal hernias, and there are two types that can form.

  • Direct. This type of inguinal hernia occurs when the abdominal muscles become weak. A portion of the intestine can push through this weakened wall and form a lump in the groin.
  • Indirect. This type of inguinal hernia occurs due to a defect during infant development. In boys, a structure called the inguinal ring allows the testicles to drop into the scrotum during development but closes after the process completes. When the ring does not close properly, a part of the intestine can push through creating a lump in the groin.

Other Groin Lump Causes

  • Lymphatic. The lymph nodes are structures that contain immune cells that fight infection and filter harmful substances from the body. When these structures become infected, they can swell and result in palpable lumps. The groin contains many lymph nodes that are susceptible to infection and swelling. If swollen lymph nodes are causing the lump in your groin, you may also experience tenderness and fever as well.
  • Cancerous. Testicular or penile cancers may also present as swollen lymph nodes in the groin, so it is very important to follow up with your doctor if you notice a lump in that area accompanied by symptoms such as pain, weight loss or dull aches in the lower abdomen.
  • Dermatologic. The groin (similar to the armpit, buttocks and under the breasts) is an area that naturally contains hair follicles surround by many oil and sweat glands. The chronic, long-term skin condition hidradenitis suppurativa can develop in such areas and result in multiple, painful and inflamed lumps under the skin. Moreover, the groin is an area often covered by clothing, which can further exacerbate this inflammatory dermatologic condition.

Top 10 Groin Lump Causes

  1. 1.Enlarged Lymph Nodes in the Groin

    Enlarged lymph nodes occur when the node becomes larger as it fills with inflammatory cells. This often is a result of an infection but can occur without a known cause.

    You should discuss with a health care provider whether or not your lymph node needs to be checked. Enlarged lymph nodes will usually shrink on their own. To speed up the process, try applying a warm, wet compress to the affected area.

    Rarity:
    Common
    Top Symptoms:
    groin lump, movable groin lump
    Symptoms that always occur with enlarged lymph nodes in the groin:
    groin lump
    Symptoms that never occur with enlarged lymph nodes in the groin:
    fever, unintentional weight loss, hard groin lump
    Urgency:
    Phone call or in-person visit
  2. 2.Genital Herpes

    Genital herpes is caused by a common viral infection that is sexually transmitted. The virus can lay dormant for months after exposure, causing itching and rash on the inner thighs or genitals. Some people carry the virus, but have no symptoms for their entire lives.

    You should visit a doctor while the rash is present, because symptoms can come and go. Depending on the severity of your symptoms, the doctor may prescribe an antiviral medication.

    Rarity:
    Common
    Top Symptoms:
    fatigue, muscle aches, fever, penis pain, groin lump
    Urgency:
    Primary care doctor
  3. 3.Indirect Hernia

    A hernia occurs when an organ or internal body part bulges through the abdominal wall. In the case of indirect hernia, the hernia is a result an improperly failed deep inguinal ring after the testicle has passed through it.

    A physician is needed to determine the course of treatment. A hernia reduction will be attempted, meaning that the bulging loop of intestine will be carefully pushed back, if possible. Then, your doctor will recommend surgery in some cases. Often, watchful waiting is the preferred route in minimally symptomatic hernias.

    Rarity:
    Common
    Top Symptoms:
    groin pain, mild groin pain, moderate groin pain, groin lump, soft groin lump
    Urgency:
    Primary care doctor
  4. 4.Mononucleosis Infection

    EBV Mononucleosis is a clinical syndrome characterized by fever, sore throat, and swollen lymph nodes.

    You should visit your primary care physician within the next 24 hours. Diagnosis is confirmed by looking for antibodies against EBV. Treatment involves supportive care (hydration, antipyretics, and analgesics, such as acetaminophen and ibuprofen). Aspirin should not be given to children because of the possibility of Reye syndrome. It is also recommended that you do not do any strenuous physical activity and contact sports in the initial 3 to 4 weeks of illness due to the potential for splenic rupture.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, abdominal pain (stomach ache), cough
    Symptoms that never occur with mononucleosis infection:
    rectal bleeding
    Urgency:
    Primary care doctor
  5. 5.Groin Hernia

    A hernia occurs when a loop of intestine bulges out through the abdominal wall. With age, the supportive tissues that keep organs within the abdomen become weaker, and the risk for a hernia increases. Groin hernias, called inguinal hernias, are the most common type. They often result due to muscle straining, such as during heavy lifting.

    A physician is needed to determine the course of treatment. A hernia reduction will be attempted, meaning that the bulging loop of intestine will be carefully pushed back, if possible. Then, your doctor will recommend surgery in some cases. Often, watchful waiting is the preferred route in minimally symptomatic hernias.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in the lower right abdomen, pain in the lower left abdomen, groin pain, testicle pain, groin lump
    Urgency:

  6. 6.Strangulated Groin Hernia

    A hernia occurs when a loop of intestine bulges out through the abdominal wall. A strangulated hernia is very serious as the trapped intestine has its blood supply cut off which can cause tissue death and permanent damage.

    This is a surgical emergency. During the procedure, a surgeon will push the bulging intestine back into it's proper place and repair the hole.

    Rarity:
    Rare
    Top Symptoms:
    nausea, nausea or vomiting, vomiting, being severely ill, groin lump
    Symptoms that always occur with strangulated groin hernia:
    severe groin pain
    Urgency:
    Hospital emergency room
  7. 7.Groin Hernia Requiring a Doctor's Examination

    A hernia occurs when a loop of intestine bulges out through the abdominal wall. With age, the supportive tissues that keep organs within the abdomen become weaker, and the risk for a hernia increases. Groin hernias, called inguinal hernias, are the most common type. They often result due to muscle straining, such as during heavy lifting.A complicated groin hernia, also called an incarcerated hernia, is a medical emergency. This type of hernia cannot be easily reduced, in other words pushed back without surgery. An incarcerated hernia is at high risk of becoming strangulated, meaning that pressure on the loop of bowel can cause the trapped segment to lose blood supply. Unless the blood supply is restored promptly, the tissue can rapidly die. This is a life-threatening condition.

    Call 911 immediately as an incarcerated groin hernia requires emergency surgery. An open-abdominal approach will likely be used to gain quick access to the trapped loop of intestine, and restore blood flow as soon as possible.

    Rarity:
    Rare
    Top Symptoms:
    nausea, nausea or vomiting, fever, groin pain, groin lump
    Urgency:
    Emergency medical service
  8. 8.Sarcoidosis

    Sarcoidosis is an inflammatory disease that most often affects the lungs and skin, but can als affect the joints.

    You should visit your physician to discuss your symptoms when convenient.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, headache, shortness of breath, loss of appetite, joint pain
    Urgency:
    Primary care doctor
  9. 9.Syphilis

    Syphilis is a sexually transmitted disease caused by bacteria. It infects the genital area, lips, mouth, or anus of both men and women.

    You should visit your primary care physician within the next 24 hours, where he/she will look for any skin changes and use screening tests to try to rule it out. If the diagnosis is confirmed (typically by a blood test), treatment would start immediately with antibiotics.

    Rarity:
    Rare
    Top Symptoms:
    groin lump
    Urgency:

Groin Lump Treatments and Relief

Since the causes of groin lumps are varied, it is important to make an appointment with your physician in order to get the proper diagnosis and treatment. Depending on the cause of your groin lump symptoms, your physician may suggest

  • Surgery. If an inguinal hernia is causing your groin lump symptoms, your physician may suggest open or non-invasive surgery to relieve discomfort and prevent complications. However, if your hernia is not causing you significant pain or discomfort, your physician may suggest watchful waiting.
  • Antibiotics. If you have swollen lymph nodes due to infection, your physician will provide appropriate antibiotic treatment.
  • Anti - inflammatory. Hidradenitis suppurativa can be treated with various types of medications that target and decrease inflammation, including immune system suppressing drugs.
  • Cancer Treatment. If your groin lump and associated symptoms are due to cancer, your physician will discuss treatment options including surgery, radiation or chemotherapy.

See your doctor as soon as possible if your groin lump is associated with symptoms such as:

  • Nausea and/or vomiting
  • Fever
  • Pain that is sudden and increases in intensity
  • Lump changes color
  • Inability to pass gas

These could be signs of an incarcerated hernia. A hernia is incarcerated when it becomes trapped in the abdominal wall. Incarcerated hernias are dangerous because they can wrap around themselves and cut off blood flow to the trapped tissue. When this occurs, a strangulated hernia results, which can have life threatening consequences if not treated promptly.
