Hello,
I didn’t have any drainage tubes, so I’m afraid I can’t help you with that question. But, I too had the gassy “bubble” feeling. It has certainly gotten better, but I still have my days. I have been on Aciphex for my stomach acids and it really has helped me. If I do not take it, I have a lot of abdominal “bubbly” sounds and a lot of gas. You might ask the doctor about some form of acid-reducer.
It sounds like your mom is doing well. I was in the hospital for 9 days, home for 9 days and back in for four days, so at the end of 2 weeks, I was actually only just getting home. I hope she feels better everyday.
We are all thinking about both of you.
Sue
