(I didn't get them until I was on it for just over 3 months.)
I put an ice pack on my injection site
for 2 minutes, then, wipe my skin with an alcohol wipe, wait for it to completely dry, then, inject.
Immediately after injection, I take a very soft, warm wash cloth and gently rub my injection site in a circular motion to disperse the medication.
I've never experienced any site reactions. And I haven't had any burning, at all.
