She received her first booster in October. She felt that with her preconditions she should get the extra booster. She had the shot on Saturday morning of 14May2022. She didn't seem to have a problem until the next day and all the sudden she got tingling in her hands and feet and it's progressed to numbness and tingling in her feet and legs. States the tingling was still in her hands. She went to the emergency room on Monday. She started to feel some weird effects on Sunday evening and decided to go to emergency room if things didn't get better. While in the emergency room, she was put in the admitting observation area so she could have a MRI and brain scan. She was released yesterday morning and her symptoms did seem to get better. She did have tingling and strange feelings, which are not back to normal, but they didn't say one way or another, it wasn't like she had a stroke because they did the brain imaging. She is still feeling a little weird as far as tingling in her hands and feet and the numbness in the left side of her face. They checked her for stroke and nothing was detected. Caller asked call handler to hold because she doesn't know who is calling and it may be the hospital and call disconnected. First outbound attempt 18May2022 at 12:48 PM, ININ: #. Reporter reached. Caller states that she had just received a follow up call from the emergency room stay. States she told them she is still feeling tingling and a little woozy-weird feeling, but not as bad as she was 2 days ago so hopefully it will disappear soon. She received the vaccine in the neighborhood this past Saturday. Her first initial Pfizer vaccine 30Jan2021 gave her ocular migraines, one episode. The Lot number is EL9264, but the expiration and NDC number are not on the card from the pharmacy. They don't put them down which is not good. She got the first and second vaccine at (Hospital Name Withheld) and the boosters she got in the neighborhood.  Reporter Details: She is retired. HCP details: Her doctor doesn't know about this. She has to tell her and she has a cardiology appointment tomorrow.

HCP permission to contact declined, she will call back in and if she has a neurologist she will report that in to us as that will probably who will, if these things persist, who she will be dealing with. Event Details: Tingling in her tongue didn't happen until today, she had it on Monday and it went away and now it's come back. The numbness in her feet up toward her knees and has to say, which she didn't have before, she developed a headache, she's in the first couple of days for the booster so she assumes things can happen while her system is reacting to the booster. Tingling in hands and feet: It's not as severe and slightly improved. Numbness in feet up toward knees: There is still slight numbness. Tingling tongue: She woke up in the morning and she was fine. Toward mid-morning it was tingling and she had that woozy feeling and it's still doing it now.
