What Is a Swollen Lymph Node in the Groin on One Side?
The lymph nodes in the groin (inguinal lymph nodes) are part of the lymphatic system and play a key role in the body's immune defense. Normally, they are not palpable. A swollen lymph node in the groin on one side – also known as unilateral inguinal lymphadenopathy – refers to the enlargement of one or more lymph nodes on only one side of the body. This can be a sign that the immune system is actively responding to an infection or another condition affecting the leg, foot, lower abdomen, or genital region.
Causes
There are many possible causes for a swollen lymph node in the groin on one side:
- Local infections: Wounds, skin infections (e.g., erysipelas), fungal infections, or infected lesions on the foot, lower leg, or genital area.
- Sexually transmitted infections (STIs): For example, syphilis, gonorrhea, genital herpes, chlamydia, or HIV can cause unilateral or bilateral lymph node swelling in the groin.
- Reactive lymphadenopathy: The immune system responds to a regional infection site without an underlying serious disease.
- Lymphoma: Both Hodgkin lymphoma and non-Hodgkin lymphoma can present with enlarged lymph nodes.
- Metastases: Tumor tissue from nearby organs (e.g., bladder, prostate, uterus, skin) can spread to the inguinal lymph nodes.
- Leishmaniasis: A parasitic disease occurring in certain parts of the world.
- Injury or trauma: Trauma to the leg or groin area can temporarily cause swelling.
Symptoms
A swollen lymph node in the groin may be accompanied by various symptoms:
- Palpable enlargement or visible bulge in the groin area
- Tenderness or a feeling of tension
- Redness and warmth of the skin over the lymph node
- General malaise or fever (with infections)
- Night sweats, weight loss, persistent fatigue (possible signs of a systemic condition)
- Skin changes or wounds in the area drained by the affected lymph node
Diagnosis
Diagnosis is made through a thorough medical examination. The following measures may be used:
- Physical examination: Palpation of the lymph nodes (size, consistency, mobility, tenderness)
- Blood tests: Complete blood count, inflammatory markers (CRP, ESR), antibody tests if infection is suspected
- Ultrasound of the groin: Assessment of the structure and size of the lymph nodes
- Swab or pathogen detection: If a sexually transmitted infection is suspected
- CT scan or MRI: If a malignant (cancerous) condition is suspected
- Lymph node biopsy: Removal of a tissue sample for histological examination when other causes have been ruled out
When to See a Doctor
A swollen lymph node in the groin should be evaluated by a doctor if:
- the swelling persists for more than two to four weeks
- the lymph node is larger than 1 cm
- the swelling is painful, hard, or immobile
- fever, night sweats, or unexplained weight loss occur
- additional wounds, discharge, or skin changes are present in the genital or leg area
Treatment
Treatment depends on the underlying cause:
- Infections: Antibiotics for bacterial infections, antiviral medications for viral causes, antifungals for fungal infections
- Sexually transmitted infections: Specific therapies depending on the pathogen (e.g., penicillin for syphilis)
- Lymphomas: Chemotherapy, radiation therapy, or immunotherapy, depending on type and stage
- Metastases: Oncological treatment of the primary tumor
- Reactive lymphadenopathy: In many cases, the swelling resolves on its own once the underlying cause is treated
