Has anyone who is doing Enbrel had any skin reactions? I've had 7 injections now and the last 4 have turned red, couple of them got sore and then when they start to fade they turn black & blue. I called the doctors office and they told me that this will happen to a percentage of patients and its nothing to worry about. Will this eventually stop happening? And does anyone know why it happens and if there's something I'm possibly doing wrong that might cause this?
