Wow, how scary! I'm so sorry for what your dad is going through. He probably had the beginnings of an infection, and the Remicade kept his body from containing it. Remicade shouldn't prevent antibiotics from working; they keep the body's natural defenses from being as strong as they could be. Abscesses are pretty difficult to treat, though. The antibiotics will have a difficult time reaching the infection sometimes.
I'm sorry I didn't have much to offer here. I will keep your dad in my prayers.
"For this thing I besought the Lord thrice that it depart from me. He said, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities; I take pleasure in infirmities, reproaches, necessities, persecutions, distresses, for when I am weak, then am I strong" 2 Corwww.thecrazyshoppingcart.com/
