Inguinal mass


There is a 2 cm raised lump near the groin area below the lower back, which is painful when standing and feels hard to the touch.
I have tried to squeeze it, resulting in pus and some bleeding.
There are also hard areas around the lump.
It has been a week since I noticed it, and it hasn't gone away.
Is this normal?

More Info


Understanding groin lumps can be crucial for identifying potential health issues. The presence of a 2 cm lump in the groin area, especially one that is hard to the touch and painful when standing, raises several concerns. The fact that you have attempted to squeeze it, resulting in pus and bleeding, indicates that this lump may be infected or inflamed.

Possible Causes of Groin Lumps
1. Lymphadenopathy: One of the most common causes of lumps in the groin area is swollen lymph nodes. This can occur due to infections (viral or bacterial), inflammatory conditions, or even malignancies. The lymph nodes can become enlarged in response to infections in the legs, abdomen, or even sexually transmitted infections.

2. Abscess: The description of pus and bleeding suggests that you may have developed an abscess, which is a localized collection of pus due to infection. Abscesses can be painful and may require drainage by a healthcare professional.

3. Hernia: A groin lump could also be a hernia, particularly if it becomes more prominent when standing or straining. Hernias occur when an organ or tissue pushes through a weak spot in the abdominal muscles.

4. Cysts: Sebaceous cysts or epidermoid cysts can also present as lumps in the groin area. These are generally benign and may become inflamed or infected.

5. Tumors: While less common, both benign and malignant tumors can present as lumps in the groin. If the lump persists or grows, further evaluation is warranted.


Symptoms to Monitor
- Pain: If the pain worsens or becomes severe, it is essential to seek medical attention.

- Fever: The presence of fever could indicate a systemic infection.

- Changes in Size: If the lump increases in size or changes in consistency, this should be evaluated.

- Discharge: Any discharge that is foul-smelling or accompanied by other systemic symptoms should be assessed by a healthcare provider.


Treatment Options
1. Observation: If the lump is small and not causing significant discomfort, your healthcare provider may recommend monitoring it for changes.

2. Antibiotics: If an infection is suspected, antibiotics may be prescribed, especially if there is evidence of an abscess.

3. Drainage: For an abscess, a healthcare professional may need to perform an incision and drainage to remove the pus and relieve pressure.

4. Surgery: If the lump is determined to be a hernia or a tumor, surgical intervention may be necessary.

5. Follow-Up: Regardless of the initial treatment, follow-up appointments are crucial to ensure that the lump is resolving and to monitor for any potential complications.


When to Seek Medical Attention
Given that the lump has persisted for over a week, has caused pain, and has resulted in discharge, it is advisable to seek medical attention promptly. A healthcare provider can perform a physical examination, possibly order imaging studies (like an ultrasound), and determine the most appropriate course of action based on the findings.

In conclusion, while some groin lumps can be benign and self-limiting, the symptoms you describe warrant further evaluation to rule out serious conditions. Early diagnosis and treatment can prevent complications and promote better health outcomes.

Without actually seeing the lesion, it is impossible to determine the issue. If it is very concerning, please seek medical attention as soon as possible. Only after an examination can the problem be identified and addressed.

Dear Kevin: It sounds like lymphadenopathy and inguinal hernia should both be considered. I recommend consulting with a hematologist-oncologist and a general surgeon. Thank you.
