1 A doctor can often identify which nerve is pinched in the neck or lower back based on what portion of the patient's arm or leg is affected. 2  A pinched nerve in the wrist from carpal tunnel syndrome typically affects the thumb, index, and middle fingers.
It is never normal to have abdominal pain, to start with. And even less to have it regularly. Bowel movement after meals is relatively normal (of course, depending on frequency, intensity, etc.), as a consequence of something called the gastrocolic reflex. Your symptoms might suggest an enhanced/exaggerated gastrocolic reflex, that is not uncommon as part of, or in relation with, an irritable bowel syndrome.
Gastricolic reflex: When you eat , you GI tract gets activated in order (mouth to rectum/anus) like a tidal wave. So you may feel like having bowel movement 30-60 min after meal. Your stool is not what you ate , is what was stored in the colon (it takes about 16-24 hrs to digest food before it turns into stool).
