• Muscle issues also called esophageal motility disorders. In people with these issues, abnormal muscle movement in the esophagus keeps nourishment from moving through the esophagus normally. Esophagus muscle issues uncoordinated muscle contractions (esophageal spasm), high-pressure contractions or contractions of the esophagus (nutcracker esophagus ), and missing contractions caused by nerve loss (achalasia). 
• Instinctive or esophageal hypersensitivity. People with this condition have lots of pain when there is an extremely little pressure change in the esophagus or a small amount of stomach corrosive comes up into the esophagus. People with a normal throat would not feel anything from the pressure change or the presence of acid. The reason why a few people have this additional sensitivity (hypersensitivity) to pressure or acid isn't known.

After the GERD side effects lessen, the portion of the PPI is decreased to the lowest amount that controls side effects. At least two months of medication treatment might be expected to control the side effects.
