Painful mass in the lower abdomen?


Doctor, I have a horizontal lump about four centimeters in size located in the lower abdomen near the penis.
It feels soft to the touch, and pressing on it causes pain.
I experience pain when I stand up after sitting or when I bend over to get up from a lying position.
There is also a mild pain when walking.
What could this issue be?

When it comes to painful lower abdominal masses, there are several potential causes that should be considered. Based on your description of a soft, painful mass located near the pubic area, it is essential to explore various possibilities, including but not limited to hernias, lymphadenopathy, cysts, or even tumors.

1. Hernias: One of the most common causes of a palpable mass in the lower abdomen is a hernia. This occurs when an internal organ or tissue bulges through a weak spot in the abdominal wall. Inguinal hernias, for example, can present as a soft mass in the groin area and may cause pain, especially when standing or lifting. If you notice that the mass changes in size with movement or pressure, this could be indicative of a hernia.

2. Lymphadenopathy: Enlarged lymph nodes can also present as masses in the lower abdomen. This can occur due to infections, inflammatory conditions, or malignancies. If the lymph nodes are swollen, they may be tender to the touch and can cause discomfort when moving or applying pressure.

3. Cysts: Another possibility is the presence of a cyst, which can form in various tissues, including the skin, ovaries, or other abdominal organs. Ovarian cysts, in particular, can cause lower abdominal pain and may be palpable if they become large enough. They can also lead to complications such as rupture or torsion, which would require immediate medical attention.

4. Tumors: While less common, tumors—benign or malignant—can also present as masses in the abdomen. These may be associated with other symptoms, such as weight loss, changes in appetite, or gastrointestinal disturbances. If the mass is firm rather than soft, or if it is growing in size, further evaluation is warranted.

5. Muscle Strain or Abdominal Wall Issues: Given that you experience pain when moving from a sitting or lying position, it is also possible that the discomfort is related to muscle strain or issues with the abdominal wall itself. This could be due to overexertion, previous injuries, or even conditions like diastasis recti, where the abdominal muscles separate.

Given the complexity of abdominal pain and masses, it is crucial to seek medical evaluation. A healthcare provider will likely perform a physical examination and may recommend imaging studies such as an ultrasound or CT scan to better visualize the mass and surrounding structures. Blood tests may also be necessary to check for signs of infection or other underlying conditions.

In summary, while there are several potential causes for the painful mass you are experiencing, it is essential to consult with a healthcare professional for a thorough evaluation and appropriate management. Early diagnosis and treatment can significantly improve outcomes, especially if the underlying cause requires intervention. If you experience worsening symptoms, such as increased pain, fever, or changes in bowel habits, seek medical attention promptly.
