crohn's disease
"It took doctors years to diagnose me with moderate to severe Crohn's.  I've been on Humira for 8 months now and I feel the best that I have ever felt.  I rarely get sick and I have more energy to keep up with my active lifestyle.  The only side effect was that I got two very small marks of psoriasis which were gone within a couple of days.  So far so good for me."
