I started Humira (1 pen every other week) in January and I've never felt better. I too was VERY nervous about
the side effects, but I'm getting blood work done on my off weeks. So far, so good.
The shot hurts, but only for about a minute. Like others are saying...make sure to take it out of the fridge 30 min. before you take the shot. I'm deathly afraid of needles, but I'm handling this fine.
Also, I too had a nurse come out to show me how to do the shots.
The only complaint I have is that I seem to be more tired now. I used to go to bed at 12am-1am. Now, I'm going to bed at 9pm-10pm and I'm still tired when I wake up.
Good luck!!
