Since the vaccination, the patient has been tested for COVID-19. It was stated that "Within a few days of receiving the second COVID vaccine, I developed severe back pain, shooting down my leg and calf. I went from walking 5 miles a day to being unable to walk. I was bent over in pain. I spent three weeks being barely able to walk or stand and unable to leave my home. It was another three weeks before I could walk 1/2 mile comfortably. I had difficulty regulating heat and cold, had hyperhydrosis, decreased appetite and lethargy. My knee and calf were swollen and discolored. I went to the ER, Physical Therapy, and finally my MD, who said it was an inflammatory reaction to the vaccine. I still have some hip, leg, and back pain. I had x-rays to confirm it was not a musculoskeletal problem. I did not hurt my back. Pain medication did little to help. Until this time, I had never had an xray. Before this I was in exceptionally good health. I have finally returned to daily walking and yoga. I am a Registered Nurse with 40-year experience and a Doctorate", in Feb2021at 05:00 AM.
