Reaction to Tdap?

Amy • Mom to 4 beautiful girls. 3/3/10, 4/27/14, 4/8/17, 3/7/19.

I got my Tdap shot this past Thursday, I still have a visible red mark about the size of a quarter around where I was given it, if I feel the spot it still feels like a hard lump underneath and I noticed yesterday it’s starting to itch around the site. I’ve never had this happen before and it’s not the first time I’ve gotten the shot. Anyone else have a similar issue?
