Any experiences with Cimzia (Certolizumab)?

My Rheumatologist is switching me from Enbrel to Cimzia for my *suspected* Crohn's to see if that helps lessen my GI symptoms.

Has anyone used it before? What do the injections feel like? On Enbrel, they burn a bit and I generally have a small injection site reaction, I am just looking to prep for these shots, but I don't know anyone who has used it before.

Thank you!
