my husband had a upper scope about 3 weeks ago, they found an infection and treated it with medication, my husband is still complaining of stomach pain so his primary doctor order him to see a specialist and they are saying they want another upper scope, my husband has lost 50 pounds in the last 4 months, his is complaining of watery stools, not feeling like he has emptied his bowel, vomiting and the pain in his stomach I wonder if he should have a colonoscopy instead of the upper GI scope
