Welcome to Crohn's Forum, a support group for people with all forms of IBD. While this community is not a substitute for doctor's advice and we cannot treat or diagnose, we find being able to communicate with others who have IBD is invaluable as we navigate our struggles and celebrate our successes. We invite you to join us.
Similar thing happened to my nephew. They found out he had exercised induced asthma. He needs to have an inhaler with him always now.
I would ring your Dr. and just make sure it is okay for you to wait until next week. I don't have any experience with Humira so I have no idea if the two could be related.
