Thank you for the query.
If you do not have any pain in this region, no pain when urinating, no pain radiating from the back, no bruise
in this area you probably do suffer from symptoms caused by this region nerves compression (probably some skin branch of genitofemoral nerve). Such diseases can be caused by pelvis muscles that compress some nerves due to longterm sitting position. In some cases tight underwear can cause such condition as well.
You may try to change your underwear or sitting position and see if this will bring some relief. You can also try some OTC Non-steroidal anti-inflammatory.
Hope this will help.
