When having Crohn's you always take the chance it will come back. He also takes the chance of having to run back to the bathroom again if he gets his reversed. He really needs to talk to his gastro doctor about it and his surgeon.
If your husband retires can he recieve medicare? Medicare pays for all supplies needed. Have you tried going to Hollister website to see what they offer? I recieve my supplies from Byram healthcare..here is a number you can call and see if they can help you..1-800-248-4525 not sure if they can but they were a big help to me before and after I recieved medicare. I only tried Hollister once and Byram changed to Convetac. I really don't remember any difference.
I change my bag anywhere from 5 to 7 days. However, I do change it every 3 days when my skin breaks down until it heals and only use paste at that time. Other then that I don't use the paste anymore.
I hope everything works out for you both...Take care and good luck...Pam
