Not too bad.
Yesterday, when I got back home, I took two Tylenol “just in case”. Turns out that was wise as the headache and arm started talking to me later in the afternoon. Throughout the night, my arm was throbbing at the injection site. Not enough to cause concern, just enough to keep me awake.
Through the morning and early afternoon my headache and throbbing arm persisted. However, around 5:00 p.m. or so, it began to subside. I think the effects are over at this point in time. I know that more will be waiting for me after the second injection.
As I said yesterday, I’m just happy that I had a chance to get my shot and will definitely complete the second round.
