thank you for your query.
A groin lump is localized swelling in the groin area which maybe firm or soft, tender or not painful at all.
most common causes are-

6.Swollen lymph glands in the groin area
the symptoms you are describing are mostly seen in infection related cases, it could be just an infected cyst
, skin infection
treatment for it includes-
1.keep the area clean, dry and let it heal.
2.You can use antiseptic solution for cleaning and then neosporin
3.If you develop fever or pus discharge, it is better to see your doctor for proper drainage
wishing you good health
