I have been on Humira for a couple of years now for my Crohn's Disease. Lately it seems like I always have an infection cooking somewhere on my body. If I rip off a hangnail, the site can become infected, sometimes I've had to even take antibiotics. Currently, I have a swollen lymph node in my neck, probably due to the severe rash/scaling on my scalp that I can't stop scratching. I thought I was told to hold off on the injection if I was sick or infected but I was wondering what anyone else's experiences are. How long can I put the shot off for, exactly?
