Hi,
The location that you have suggested is associated with various body organs and therefore many conditions may
be reflected here.
Infections in the skin overlying the area, hernia, lymph node swelling due to infection or cancer, underlying
subcutaneous tissue infection are some of them.
It is important that the doctor examine and test put the various possible diagnosis to reach out the final one
and thereafter start treatment for this.
Have you observed any menstrual, obstetric or gynecological changes?
have you had constipation, diarrheas, nausea, urinary problems etc?
has the area liberated any pus or blood?
The answers to these questions will help us understand the condition better. I think you may have to go to a
doctor to get this examined afterall.
Hope thsi helped. let me know if you may need more help.
