When they say don't inject yourself if the Humira window is cloudy, what exactly does that mean? When I take my Humira pens out of the refrigerator, the window isn't exactly see through. It looks like a cool glass of water. Not sure if it's condensation or not. I just want to make sure I'm not injecting myself with something I'm not supposed to be. I just took the injection about 15 minutes ago.
