The leakage from the tube is normal. Not a reason for concern. Whenever you have the tube open always keep the open end up high, otherwise the contents of your stomach with drip/run out. For me, the pain let up completely with in one week. Have him stay away from carbinated drinks and gassy foods. They are not his friend! I experienced a bit of pain each time I ate during the first week or two. It was explained to me that the stomach moves around as it is going through digestion, and this PEG sort of tethers it down, therefore making it hurt. Good luck to you and him both. I saw all the work my husband did for me.....I saw the pain in his eyes as he hurt for me. It takes a heart of steel to be a caregiver....you, too endure alot.
