@rritam, you're correct. Abdominal wall pain is a common and often underrecognized cause of chronic abdominal pain. Like any underrecognized symptom or condition, whether common or rare, there is an unwelcome burden beyond illness placed on the patient. Often it is the patient who contributes knowledge of the pain, research from internet or library sources, and anecdotal evidence from forums like this one to their health care team to help investigate and diagnose abdominal wall conditions such as ACNES (anterior cutaneous nerve entrapment syndrome).

In addition to the Dutch paper you cite and work by the American Academy of Family Physicians (https://www.aafp.org/afp/2001/0801/p431.html), Mayo Clinic provides continuing medical education about ACNES for internal medicine physicians and other clinicians who wish to advance their current knowledge of clinical medicine and who wish to stay abreast of advances in medical research. See Mayo Clinic Proceedings here: https://www.mayoclinicproceedings.org/article/S0025-6196(18)30671-2/fulltext

Patients working their doctors today pave the way for better knowledge and understanding for patients in the future. @rritam, what do you advise fellow patients when they suspect ACNES as a possible diagnosis?
