Next day body aches, slight headache, tired. Yesterday body pain, like the most intense workout of my life.  I couldn't get up.  No energy and horrible headache. I've been taking Tylenol since Friday. Saturday slight chills, burning up and then cold chills. Yesterday could not get warm- freezing all day. Temperature was normal but I've been taking Tylenol. Hurting and headache and dizziness this morning.  it seems like each day something adds on.  Is this normal? Reported she got her second Pfizer COVID-19 Vaccine shot on Friday (12Mar2021). She said she heard nothing bad happens after getting the Pfizer COVID-19 Vaccine, and if there are side effects, the side effects would only be a day or two. She said she was on day 3 of having side effects after her second COVID-19 Vaccine. She said she maybe fine, but wanted to make sure what she was experiencing were expected side effects for the COVID-19 Vaccine. She said she was a school teacher, and didn't want to go to school today because of how she was feeling. She said her arm (left) was hurting after her second COVID-19 Vaccine, but she was OK with her arm hurting. She said her arm (right) hurt, too, after her first COVID-19 Vaccine. She clarified after her first COVID-19 Vaccine, she had only right arm soreness. She said the right arm soreness was bad. She said she wasn't used to that type of arm soreness after a vaccine, though she was expecting some type of arm soreness. She said her right arm soreness went away after a couple of days. She said her arm hurting was an expected side effect of the COVID-19 Vaccine. She said her body ached, as well, after the second COVID-19 Vaccine. She said she anticipated body aches, and took Tylenol, and rested a bit. She said she was extremely tired, too. She said each day she had something additional she was experiencing. She said she had no energy yesterday (14Mar2021), and her body aches had progressed to her body being in pain. She said her body pain hurts worse than the pain she would experience from working out. She said she had a light headache yesterday (14Mar2021), and when she got up this morning, she became dizzy. She said she each day she was getting more side effects. She said she was still taking Tylenol. She said she doesn't have a fever, but wasn't sure if that was because she had been taking Tylenol for her pain. She said she read it was OK to take Tylenol with the COVID-19 Vaccine, so she took Tylenol on her way to get her second COVID-19 Vaccine on Friday (12Mar2021). She said the next day (13Mar2021), she took a shower in the morning, and took Tylenol again. She clarified she had been taking Tylenol every day since she received her second COVID-19 Vaccine.
