I've never really understood why some GIs have nurses come to administer these shots. They are designed for non-medical people to administer and very easy. IMO the Cimzia package is like "shots for dummies" LOL. It's designed for you to do at home alone. The Humira was not hard to understand but not as user friendly in the packaging.
Cimzia was easier than Humira for me - mostly because Humira hurt and Cimzia didn't. Cimzia is very thick so you have to use some force. No biggie, though.
