sarahfh, we had two infections after her GJ tube was put in. Same situation as you. It took us a while to figure it out. Now when she thinks it's getting infected, we use an antibiotic cream and usually it goes away. It's also sometimes difficult to tell pus from discharge. You can have discharge that looks a lot like pus, but it isn't. It took us a while to figure out what was normal for her and what was suspicious. It helps too if you have other symptoms - redness around the stoma for example.I'm doing okay thanks, I finally had a GJ tube placed on February 27th, it's been a bit rocky with an infection in it so I've had weeks of iodine dressings and antibiotics and I'm still getting puss draining from it which is frustrating. But overall it's so much better than the NJ was!
In terms of pain, my daughter took several months to heal fully but I think that's because she was on biologics. She required pain meds too. I am surprised you're having trouble weaning the Tramadol though - 50 mg twice a day isn't a high dose at all. But everyone is different.
Pain meds are weird though - my daughter has been on high doses of pain meds due to arthritis damage in her joints (she will be having her 3rd surgery in less than a year this summer :ybatty and active AS. But her Gastroparesis hasn't been bad at all this year! In fact, she is finally eating and not using her tube! Totally bizarre.
