This may seem trivial but I was wondering what advice anyone has on dealing with being ill on top of the vasculitis. I have my first cold since being diagnosed in Feb '11 with Wegener's, and I feel absolutely dreadful! I know that's par for the course with a cold but I'm worrying anyway. My eyes have inflamed which I've been given drops for, but will my body even be fighting it off? Do I technically have a functioning immune system to deal with it while taking Azathioprine? Also I'm due to have a blood test later this week to check my compatibility for the drug, will my cold interfere with the results in anyway? I'm seeing my GP tomorrow but how does everyone cope with other illnesses that come along?
