Painful Groin Bumps: Causes and When to Seek Help

A painful lump has appeared in the groin area?

Hello Doctor: For the past year or two, I have frequently developed a painful lump in the left groin area (upper thigh) before and after my menstrual period.
It appears slightly red or skin-colored, has no head to squeeze (it seems to be growing under the skin), and it grows to a certain size before shrinking on its own.
Whether I ignore it or apply some medication, it eventually resolves itself.
However, this time it's unusual as two lumps have appeared (one small and one larger).
The larger one causes pain when I walk due to friction, and the smaller one is painful to the touch! Last month, when I had one, I visited a dermatology clinic, and the doctor said it was nothing to worry about.
If I wanted to have it surgically removed, that was an option, but it could also be left alone, or I could wait until it abscesses.
What does that mean? What does it mean to wait for it to abscess? Now, I have two lumps at once? Is it really nothing to worry about? I have been applying ointment, and they are gradually shrinking and disappearing, but the high recurrence rate is quite concerning! Is this related to my habit of picking at my feet (which often leads to wounds—what a terrible habit)? Do I need to see a surgeon again? Based on my symptoms, what exactly is growing in my case?

Hello, regarding your question, I would like to respond as follows: Due to the descriptions in your letter, it is not clear what the lesion looks like and its exact location (is it on the thigh or in the groin? The diseases associated with lesions in these two areas are completely different), so I cannot provide you with an accurate diagnosis.
Therefore, I cannot inform you whether your condition is related to frequent scratching of the feet.
Common painful skin lesions include vascular lipomas, certain types of hemangiomas, leiomyomas, and neuromas, among others.
Additionally, swollen lymph nodes and some skin infections can present similar symptoms.
I recommend that you consult a dermatologist nearby for an accurate diagnosis, which will help determine how to proceed with your situation.
Wishing you a happy and healthy New Year.

More Info

Understanding painful groin bumps can be quite concerning, especially when they recur frequently. Based on your description, it sounds like you may be experiencing a condition known as a sebaceous cyst or possibly an ingrown hair. These bumps can appear in the groin area and are often benign, but they can cause discomfort, especially if they become inflamed or infected.

Sebaceous cysts are small lumps beneath the skin that can occur when the sebaceous gland becomes blocked. They are typically filled with a substance called sebum, which is produced by the skin. These cysts can become red and painful if they become infected, leading to what is known as an abscess. An abscess is a collection of pus that forms due to infection, and it can be quite painful. If a cyst or bump becomes abscessed, it may require drainage by a healthcare professional.

In your case, the fact that these bumps appear before or after your menstrual cycle could suggest a hormonal influence, which is not uncommon. Hormonal changes can lead to increased oil production in the skin, potentially contributing to the formation of cysts or acne-like lesions. The bumps you describe as painful and red could also be related to friction from clothing or activities, especially if they are located in an area that experiences a lot of movement.

You mentioned that you have a habit of picking at your skin, which can lead to skin irritation and potential infections. This behavior can exacerbate existing conditions and lead to new bumps forming. It’s essential to avoid picking at any lesions, as this can introduce bacteria and lead to further complications.

Regarding your visit to the dermatologist, it’s good that you sought professional advice. The recommendation to monitor the bumps and consider surgical removal if they become problematic is a common approach. If these bumps are not causing significant issues and are resolving on their own, it may not be necessary to pursue aggressive treatment. However, if they continue to recur or if you notice any changes in size, color, or pain level, it would be wise to follow up with a healthcare provider.

If you are experiencing significant discomfort or if the bumps are not resolving, it may be beneficial to consult with a surgeon or a dermatologist again. They can provide a more thorough examination and may recommend further treatment options, such as drainage or removal of the cysts if they are recurrent and bothersome.

In summary, while it sounds like the bumps you are experiencing are likely benign, it’s essential to monitor them closely. Avoid picking at the area, maintain good hygiene, and consider consulting with a healthcare professional if the bumps persist or worsen. Keeping track of any changes and discussing them with your doctor will help ensure that you receive appropriate care and peace of mind.
