[Howdy Y'all]

I just recently started remicade infusions a month ago due to my crohn's disease. However I'm not sure if I should continue. Always after the infusions, I feel a lot better for a week. Then Im in so much pain until a week before my next infusion. For example it has been 4 weeks since my last infusion. The 1st week I felt better, then the 2nd and 3rd week I was in so so much pain, even more pain than before I started remicade, then the 4th week I feel better. Except since I started air comes out when I pee and sometimes my urine color is a little brown. I'm deciding whether or not to go to my next infusion. Is the pain I get just temporary? Why am I only out of pain the first week of the infusion and the last week before I get my next infusion? Should I stop remicade or should I continue going?
