The patient underwent shoulder and neck x-ray in May2021 result arthritis. It was also reported as January and early February, he was out walking 4 to 6 miles a day, not having any real problems. He had the Pfizer vaccine both shots and he did not have any problem at the time of the shot, his arm didnt get sore, he didnt have any problems at all. Fast forward a couple of months, he was very fatigued, tired, had no energy, sleeping from 12 to 16 hours a day and very lethargic and then his muscles and joints started to ache like crazy, pain in his shoulders, and now if he walks a mile thats a long walk for him, hes very tired. He has lost 4 to 5 pounds in the last couple of months, he just wonders if this Pfizer vaccine is causing his antibodies to kick against itself. He went to the emergency room about 2 to 3 weeks ago, they did x-rays of the neck and shoulders because it was bad. He had some arthritis and sent him to physical therapy because he cant lift his arms up above his chest. His muscles are starting to hurt and as long as he is up and moving, he is not as bad. When he lays down at 10:00 PM at night to go to sleep, he is up at 12:00 in pain. He got his shots in February, and in April it started, so it was like a couple of months after the shot because he went online and they said side effects usually last one to two weeks right after it, but he didn't have anything right after, but then 2 months after, he started getting really tired and aching and then the pain came. The pain in his shoulders, muscles from his groin to his thigh, it's in his hands when he wakes up in the morning. Once he starts moving things, it's okay. The pain also began in the first two weeks of April. He's tired still and aching but could be due to the fact that he doesn't get good sleep at night, if he was sleeping all night then maybe he wouldn't be as tired. Fatigue, tiredness has gotten better, its improved. But the pain is getting worse; sometimes he will be lying in bed at night and the bottom of his feet will start to grab and cramp up and hurt. The events required a visit to Emergency Room; he doesnt really remember when he went, he knows its been over two weeks ago. The first part of MAY 2021, they did an x-ray on the shoulder and neck, that's where the greatest pain was, and all they saw was arthritis. They scheduled physical therapy and he started physical therapy and did that for two weeks but that has not done anything. He has continued with physical therapy while doctors start doing other checks. The patient called physician today and he is having blood work done this week and they are having a CT scan done next week. Outcome of the events arthritis and when he lays down at 10:00 PM at night to go to sleep, he is up at 12:00 in pain was unknown.; Sender's Comments: Linked Report(s) : US-PFIZER INC-2021542938 Same reporter/drug/event, different patients;US-PFIZER INC-2021542943 Same reporter/drug/event, different patients;US-PFIZER INC-2021542944 Same reporter/drug/event, different patients;US-PFIZER INC-2021542945 Same reporter/drug/event, different patients
