Question
Hi. 2 weeks ago my leg started itching under the skin. Within days, I noticed small hard swollen bumps under my skin between my inner thigh and scrotum. It felt like small beans were under my skin, itched and was unpleasant. Mainly on one leg, but a few on the other leg as well. Within a week most had gone away. But there is still one swollen or hard bean under the skin on each leg right where the scrotum attaches to the inner thigh. They don't hurt, but I can feel them. Also they are basically in the exact same location on each side of the scrotum. Some days they feel more swollen, and other days they are smaller. It has been 20 days since I first noticed them. Any idea what this might be? It is not a rash and seems to be swelling or infection from within.

Hi there.

Thanks for the query.

You have provided with good information and I appreciate it. In order to guide you appropriately, I will need a few more details regarding your problem, so please answer the following questions in as much detail as possible.

Is there any scaling, discharge or bleeding from the area of skin involved between your inner thigh and scrotum ?

Are you on any medication ?

It appears that the clinical picture described resembles fungal infection of the groin area. This is called Tinea cruris.

It is caused due to sweat accumulation due to improper hygiene and lack of changing underwear and clothing for long periods. The mild swelling is caused probably due to secondary infection of skin ans subcutaneous tissue due to the chronic scratching.

You need to keep the area clean and dry. Change your underwear everyday. You may apply mild lactocalamine lotion for relief from itching and pain.

It would be best to consult a Dermatologist and get your lesions looked at for proper diagnosis and management. In most cases, anti-fungal treatment will be prescribed and sometimes disposable underwear use will help to clear infection faster.

I hope I have answered your query. I will be available to answer your follow up queries.

Regards,

There is no scaling, no rash, and no bleeding. This is part of why i am confused. It does not seem to be a rash or jock itch. It is not a sore or lesion either. The skin appears normal. The problem is hidden multiple layers under the skin. Showers occurred daily, and underwear changed daily even before this occurred. (I am a clean freak and enjoy long daily showers).
However, it feels as if a small bean or pea was implanted under the skin on each side of the leg/scrotum. If I poke it or squeeze the surrounding skin the "bean" seems to become slightly more swollen, but the surrounding skin remains normal. Perhaps a lympnode or a swollen gland? It does not itch or burn anymore. I can only feel the pressure, as the small bean shaped object or swollen gland is abnormal and my body senses the abnormal feeling of pressure.

Hi there,

If there are no skin changes, then lymph node enlargement is most likely. Lymph node there can get enlarged as a result of infection of feet, legs or genitourinary infection. Sometimes you may have similar swellings in the groin area and other parts of the body. If you have multiple lumps, visit your doctor for evaluation. A single lymph node enlargement in the groin is harmless condition.

Another possibility that needs consideration is possible chronic inflammation as a result of minor trauma. Mild inflammation can produce symptoms as you described. They do not pose any harm either.

A careful examination of the affected region by a dermatologist will help in determining the true nature of the lesion.

Hope this answers your query. Let me know if you have any more concerns.

Wish you good health.
