ankylosing spondylitis
"I was diagnosed with AS about 8 years ago.  I have been on Enbrel for approximately 7 years, except when pregnant or breastfeeding.  Enbrel worked wonders for me.  I felt great!  Unfortunately it looks like I have become allergic to something (probably preservatives) in the injection.  I had a several allergic reaction about a month ago and my doctor switched me to Humira.  I just took my first injection this past week and so far so good.  Hopefully I won't have a reaction like I recently experienced with Enbrel - keeping my fingers crossed!"
