Hello, as stated above you are suffering from chronic constipation
from 8 months.Your blood tests and x ray of colonic tests were normal.You were prescribed neopride,which is generally given for functional intestinal problems like IBS(irritable bowel syndrome
But be precise what blood tests were done and was it a normal x ray or barium meal
.You are on neopride for 15 days still no relief then i suggest you to undergo ultrasound
abdomen and any further clarification consult your doctor .take care........
