I had my feeding tube in for 2 months. I had drainage that almost looked like mucous. I had to change my gauze every day, sometimes 2 times a day due to drainage. I would talk to your doctor about it though just to make sure it's not infected. I know I contracted c-diff when they put mine in and I was in the hospital for 5 days after they put it in. Docs didn't catch the c-diff until after they removed my tube because i ended up with pneumotosis intestinalis which is very rare to get when you're "healthy" and never had any bowel problems before.
Not saying it is c-diff, but could be something else, cuz it's pretty easy for bacteria and other nastyness to get in there.
I also cleaned my site one to two times a day, and had to put a steroid gel around it due to a rash I got.
But if you are concerned talk with your doctor.
Best of luck and keep us updated, . I know what you mean about the weight loss, i lost almost 70 lbs. Was all muscle which is sad, but that's what happens when you can't get out of bed, and aren't eating enough calories.
Take care
