I am getting ready to take my 3rd series of Humira tomorrow. I noticed I have a dole headache all most always, I can't sleep and I am always tired. I also noticed my vision is very blurry lately and only seems to be getting worse. By the end of the day everything is a blur. I start off the day ok and gradually my vision becomes blurry is this normal with humira or crohns/uc in general. I have been diagnosed with crohns for 21 years and was diagnosed with UC 2 years ago during a colonoscopy.
