So I got a flu shot...
And I forgot about the cotton and bandage over the injection site. I got used to the bandage being there but when I removed it, I really noticed it. I didn't have an injection site reaction, if there is even any soreness it's not enough to be notices. In fact, I couldn't find the injection site. I only knew it was between the two spots where the bandage adhesive had been. Those were obvious.
