Hi,
I've had crohn's for 30 years and have never had a problem with headaches until I started Humira. My GI told me it is definately a side effect of the medication. They have not become bad enough that I am willing to discontinue the Humira. I do notice though that there is a pattern meaning I know I will get a headache within 2 hours of taking my needle. I notice that I also cough more with the Humira.
Hope this helps.
Julia
