She had sore joints and a lot of swelling to her face and face swelling was on one side and she had pain. She had sore elbows and all over pain. She noticed pain shortly after the second booster vaccine and she had been reading about this and thought she would notify someone about this and she said that some symptoms could be from the vaccine. She had appointment with the Rheumatologist and a Physician and no diagnosis for this and her labs had been off. The last lab was off a bit and she had not figured out herself and she was waiting for doctor and her next appointment was 18Jun and she had seen other doctors and she went to the emergency room and she had seen an Orthopedic because she had a problem with her foot. Some pain in left foot and eased up and got worse and when visited ER and couldn't walk hurt pain.

She told the doctor and doctor was busy and it was hard to see a specialist. X-ray of the ankle and CAT scan of the ankle and she went to the hospital for pain. Hospital date was unknown. She said she was not admitted but she went to the emergency room. She went for pain medication and received one dose of Cortisone for her ankle. X-ray that was negative. CAT scan that was negative. Doctors were concerned with one of her labs they did, but she didn't remember what it was. It might be autoimmune, might be it caused by the vaccine, they didn't know. She was never asked the question if she was vaccinated or not when she went to the hospital. The joint pain had gotten worse. She did not know if it was connected to the vaccine or not. She had an x-ray that was negative in the emergency department, and they sent her home. She went to an orthopedic doctor and the CAT scan was negative there. But pain had not gone away. Today was one of the worst days.
