It was reported that in the first two weeks, patient had no symptoms, no side effects at all. And then exactly on the 3rd week, three weeks after the shot, on 20Feb2021 night, patient woke up with terrible shoulder pain, like arthritis in his right shoulder and the next day it was in the left shoulder and then in my left wrist and then in his right wrist and hands. Both hands, wrists and his fingers have been the worst of all. They also run in both of his knees, feet and his groin and hip. So, it sounded like Polyarthritis or Rheumatoid arthritis. Patient had an episode of something like that about 6 years ago. It was reported that patient woke up with terrible shoulder pain, like arthritis in right shoulder and left shoulder and then left wrist and then right wrist on 20Feb2021. And now at the time of report he had tremendous pain and it has been more than a week then. Right then, he couldn't hold a pencil or toothbrush and his fingers and wrists were definitely the worst of everything. Patient was also on Plavix because had stents put in his heart on New Year's Day. Patient was on Plavix which was a blood thinner and was afraid to take some pain medications. The last time, patient took prednisone to make it better, which was a steroid but when he googled Prednisone, it said that it might decrease the efficacy of the vaccine. Patient further stated, he was totally isolated. He and his wife hadn't been out of the house except to get the vaccine. So, they were not near to anybody and don't need to go near to anybody. Patient wanted to know if he takes the prednisone would that going to effect the vaccine. He was just going to have to the painkillers instead if vaccine was getting effected because of prednisone. It was reported that holding onto the telephone was intrusively painful. Patient was in agony and was hurting. He could not hold the phone and he was on speaker. The outcome of the events was unknown.  No follow-up attempts are possible. No further information is expected.
