Hi, all! Just got home from an appointment with my gastro. I've been on Humira for about 2 months now and I've had recurring abscesses during that time. I have a Crohn's diagnosis and have been dealing with abscess/fistula for 5 years. It is currently my worst symptom. I'm scheduled December 3rd for a colonoscopy to see if the inflammation has subsided by taking Humira. If it hasn't and my abscesses continue to come back, my gastro said today that the next line of therapy is TPN. Have any of you tried it and had success with it for treating fistula? Your experiences and advice are greatly appreciated. Thank you!
