Why I'm scared of my shot

Here's a picture of what the area looks like, about an hour after I do my shot. There are a few side effects that go with it: Fever at injection site (check), fever (check), redness and swelling at injection site (check, check).

While I do get almost all the side effects they warn about, they're still not what scares me the most. What they don't tell you is that, when you do your shot (or at least when I do mine), someone always randomly bumps that area, every time...

Since starting my shots again (I'll save that story for another time), my husband has squeezed both arms, boys have push my hip, and tonight my husband got my attention by (what he says) "lightly" tapping my leg to look at something.
