I have been on cimzia next month will be a year. I have never hit a blood vessel so I'm not sure????
I usually inject them in my upper tighs and yes I have problems with it burning. My right leg is always
good but for some reason my left leg always burns some. Sometimes I will inject right leg and left
stomach a good ways away from belly button and it doesn't hurt. You should check out the cimzia
link and watch how and where to inject.
