We got the 2nd COVID vaccine yesterday... Pfizer. DH had no reaction whatsoever and initially I felt nothing but as the day wore on I felt like someone hit me in the arm with a baseball bat! I could not have dressed myself earlier today .. it was so painful. So, I took some Ibuprofen and it is much better. We both feel a bit tired but that is no big deal. I am glad it is over. It turned out much better than I could have hoped. DS and GD are coming in 10 days. Then I plan on getting a haircut and starting back at the gym. YLMV
