... I will do my second injection tomorrow, and I'm nervous. The first one I did at the doctor's office, but I was nervous then too and don't remember everything they told me. Do I have to look for bubbles in the liquid, or check to make sure it's not cloudy? Do I rub the injection site after the injection? Are there methods you use to make it less painful or more effective? Is there anything else I should do or look for before injection?
