Thought to herself, well its normal to go to sleep and hurt a little bit, but the next day it will be better. Instead, she states she is still swollen and red. She had the runs and she feels kind of sick, She is not real, real sick but she is sick enough to want to stay in her room. Reporter details: The reporter states she does not live in an assisted living facility, but she is living in a place with 130 other people. It's like an apartment building. Reporter doesn't have an email to include for the report. Healthcare Professional: The caller mentions she sees doctors. They know everything and have a big list of all of her stuff any time she goes to see a doctor. No further contact information is known. The reporter states for some reason she couldn't remember getting a vaccine record card with her second dose, so they had to look her information up in a computer and gave her a new card with her third shot. The reporter states her arm is still warm where she got the shot. It's definitely swollen and red. She expected it to go away but it hasn't so far, not that she minds. Attempted to clarify what the reporter meant by stating she had the runs, but reporter continuously stated she had the runs. She had to go to the bathroom. Generally, she didn't feel that great and wanted to be near the bathroom. She wanted to stay in her apartment and not go out. The reporter mentions she also had a back ache, but that started before she got the shot. She states she is getting to the age where it feels as if it hurts especially after she sits. When she goes to get up, she has to limp to wherever it is she is going. She mentions she still drives, not that she cares to go out right now. The reporter confirms she believes she is also considered compromised because in 1997 had a virus called Guillain-Barre. She was paralyzed for about 6 months and they say she shouldn't have a flu shot, but she  wanted the virus shot because it's more important.   No follow-up attempts are possible. No further information is expected.
