The patient received the second vaccine on 17Feb2021. A week out or so she started having pain in her feet and she was very fatigued 19Mar2021; both still ongoing, both on a week. The patient had had 2 stints at the hospital, and 2 rehabs. Both of these have very slightly improved. The patient went to the hospital due to the pain in her feet that moved up to her hands, she was very fatigued, and she couldn't walk; she was bedridden on 19Mar2021. Weeks after the shot it continued day after day after day up until 19Mar2021 where she was admitted to the hospital. The patient just had her last stint in rehab this past 2 weeks and could get up with physical therapy. Hospitalization was from 19Mar2021 to 27Mar2021. The patient could not urinate properly, she couldn't void all the way and that this occurred some time between after the second vaccine up until 19Mar2021. Those few weeks things progressed. Now she was incontinent and had to wear diapers. She urinates in diapers and defecates in diapers. The incontinence started sometime during 19Mar2021 to 27Mar2021 and it is ongoing, persisting. In the hospital they could not find anything seriously wrong with her. The patient had total fatigue and the caller begged them to give her mother a (vitamin) B12 shot. They gave it to her but there was no improvement with patient's energy. They put a catheter in her to get her kidney function back to her normal level. It was because she was not urinating properly. They ran a bunch of tests and there was not anything wrong with her. They did cardiac tests, lung tests, and XRays. The patient's breathing was labored. Started sometime after the second shot leading up to the hospital and that the patient had to be on oxygen. She said she was still on oxygen and that the labored breathing was ongoing, persisting. Reporter said all of these above listed were from 25Apr2021 to 03May2021. They did more tests but there were no answers and patient was at this point bedridden all this time; she had no strength at all, all the same symptoms were ongoing, there were no diagnoses, they were switching her meds around. The patient was on oxygen 24/7, all day when she was walking, sitting in a room in her wheelchair. The caller said she was hoping patient could get up and walk around but she was still weak. She said with time she hoped she got better on feet, got back to her normal. The outcome of the events were not resolved. Information on the lot/batch number has been requested.
