ACNES (Anterior Cutaneous Nerve Entrapment Syndrome)

What is Anterior Cutaneous Nerve Entrapment Syndrome?

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. Dr. Jacob is an expert at treating ACNES in NYC and the surrounding areas.

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.

Management of ACNES Symptoms

Injections with numbing medicine will help temporarily, but can really help with making the diagnosis.

Treatment can be with nerve ablation by a pain management specialist, or with surgery by a general or neurosurgeon.
