Adverse event: 2 days after the shot patient had extreme weakness in my right foot like I had broken my foot or ankle and patient thought he did exactly that and did not ascribe it to the shot, as patient slightly overweight and was trying to pursue the same physical fitness regimen that patient did when he was not overweight. he could barely walk on the foot for 2 days. Then it happened again in Apr2022, and he thought it was the same injury that came back. This time it was worse and he could not walk at all for 2 days. Patient needed to buy crutches. Patient right foot was slightly swollen and there was a big red mark. He did not go to the doctor for any of this because again he thought it was a fracture that would heal. But now the same pain/tightness/weakness has happened in Patient left foot and Patient reassessing those events. He think they are all related and have to do with the covid shot since the first time was a day or 2 after the shot. Patient not taking any medication.
