So I'm pretty used to injecting Enbrel. I've been doing it for 9 years now (I just counted - yikes! 9 years!) and I don't really think about it anymore.
Tonight I must have gotten the angle wrong or something, because I suddenly noticed that as I pushed down the plunger, the drug was bubbling back up through my pores! I've never seen it do that before. Hundreds of dollars, sliding down my leg. Oops.
I'm guessing I jabbed it in at less than the recommended 45 degree angle, and it ended up too close to the surface of my skin. I will pay more attention next time - no more injections while I'm watching TV/talking on the phone/in the middle of the night when I'm half asleep.
