Hi there. I'm a 24 year old female and I was diagnosed with Ankylosing Spondylitis when I was 16. I had a terrible falre this past fall and had to be on pral prednisone for 4.5 months until my new medication started working (it's called Orencia and I get IV infusions every month). I've been off of steroids for about 4 months now. The pain is much better, but I have been incredibly fatigued, drinking water CONSTANTLY, going to the bathroom more, having bad headaches, and I also get dizzy easily. My poop was also green for 4 days. Do you know what this could mean?
