What is ACNES?
Also known as a trapped, inflamed, or pinched nerve, anterior cutaneous nerve entrapment syndrome, or ACNES, can occur in the upper or lower abdomen, as well as in the groin and cause groin pain.
A tear in the external oblique fascia or nearby scar tissue can trap or pinch a nearby or penetrating unnamed nerve branch.
The pain is usually constant, and worse when the spot of the pain location is pressed on or with certain movements. The pain can radiate or be in one spot.
Imaging is usually normal.
