mild pain burping after food
The sphincter of Oddi regulates the passage of pancreatic juices and bile into the duodenum of the small intestine.
the pyloric sphincter regulates the speed at which the chyme (mixture of food from stomach) can enter into the small intestine to be digested. The pyloric sphincter opens and closes according to the acidity of the chyme.
Sphincter deficiency can result directly from pelvic fracture; urethral reconstruction; prostate surgeries; spinal cord injury; neurogenic bladder conditions that include sphincter dysfunction; and some congential conditions.
Absolutely! It can spasm and cause bile to back up. The pain in intense and sharp usually radiating to the back.
During peristalsis, the esophageal sphincter allows the food bolus to pass into the stomach. It prevents chyme, a mixture of bolus, stomach acid, and digestive enzymes, from returning up the esophagus. An overly loose esophageal sphincter leads to heart burn because the stomach acid "burns" the esophagus. An overly tight esophageal sphincter is known as achalasia and leads to pain on swallowing, regurgitation of food, and cheat pain.
Bile is produced in the liver and stored in the gall bladder. The presence of lipids in the duodenum causes the release of bile. Ultimately the liver and gall bladder control the release of bile.
Inflammation causes pain on movement.

Increasing urine pressure due to contraction of the full bladder
I think any pain in โany handโ causes pain in both hands.
