16 hours later

A few hours after the shot, my arm got sore. It hurt enough I ended up taking painkillers this morning, which didn't get rid of the pain completely, but I think it lessened it at least. It's probably making typing easier. So far I've haven't any other real side-effects. I did feel a little tired last night and a little headachey this morning, but that could easily be due to stress and sinuses.
