OK I have had my husband in the hospital 3 times in the past month ,first time he had internal bleeding due to an ulcer ( so they said ) then a week or so later he developed a lot of pain in his upper right side , we went to the er and they put in the hospital they could find no reason for the pain but took out his gallbladder to see if that was it .a week and half afterward he was still hurting badly he had a regular doctors appt and he was still in severe pain couldn't hold down any food at all or liquid prior to this he was barely eating anyway which is odd because he is a big eater, so doctor put him back in the hospital was checking him out and they found fluid under his liver which they say was fluid from having the gallbladder removed so they then put a drain tube in him he spent another week in the hospital and is home now with this drain tube but he has no energy, no appetite , is very pale and in intense pain and it hurts him to take a deep breath... do u know of anything this could be ? Because these doctors seem clueless -

This is too serious for anyone online to guess. He needs series of medical tests, review of prior treatments. He needs to be back to doctor

Thing is they have ran test and say nothing is wrong but he is so sick I am very worried :( I was just trying to get some sort of idea of possible causes...

With his problem is suggest a very serious change in his diet. Talk to the doctor about more friendly digestive foods
