I have never had a flu shot.Has anyone had the new flu shot that is not injected into the muscle, only the first few layers of the dermis? Got one yesterday, and it is really different. Usually, by my second day with the IM shot, my arm is sore as heck but, today, I barely notice where it was given. I was expecting to still be miserable. The med still stings a little when it goes in, and I'm a good one for saying "Ow!" anyway, but it is a whole different experence. Won't say it's "painfree", but it is definitely an improvement.
