On 03May2021, 23:30, she was dizzy, and was weak after second dose. What started it was she got really bad chills, she tried to get up and was dizzy, felt like she couldn't stand up without holding onto something. The dizziness was ongoing maybe a little bit, probably related to the fact she can't eat more than the vaccination itself. She stated the dizziness was probably a lot less, and she was able to walk around now. Her bad chills were not ongoing and didn't last all that long. It lasted an hour that night of 03May2021 and she had chills again yesterday, 04May2021, when fever was going back up. They were really not that bad and stated that chills were gone now and recovered completely. On 03May2021, 23:30, her arm was sore; she reported that it started hurting all at once 23:30 on 03May2021. It was pretty severe, felt like entire arm it went through, it wasn't just like it went through to inside of her arm. It was where lymph nodes were and partially across chest.

Patient reported that she has had heart burn before but she doesn't typically suffer from it and this was beyond, extremely painful. The events lasted about an hour. She immediately took some antacid tablets, but they did not work. Her husband got her Tagamet, by the time the she took it she felt a lot better. The patient guessed that she recovered with lasting effects. She tried to drink plain broth with nothing, no noodles. This was why she called because acid started jumping up into her throat from drinking that. She was afraid to eat, and she was going to have to eat at some point. On 04May2021, the patient almost passed out at one point, felt like she was going to pee her pants because of the pain, and it hurts so bad. She was close to calling 911 it was scaring her that much. This occurred after she had just eaten a small roll with butter on it. She also had fever of 101 all day, Tuesday (04May2021). She doesn't know when this began, and she finally took temperature mid-day, husband bought a new thermometer and she didn't realize she had a fever. She was taking Tylenol every 8 hours. She wondered if the Tylenol bothered her, she doesn't usually take Tylenol and she was told not to take Ibuprofen by the lady who gave her the second dose vaccination. She did take one Ibuprofen last night because she was feeling terrible and she felt a lot better. The events did not required a visit to the emergency room or physician office.
