He told the patient that the listed symptoms sounded like her and the patient stated that she did had fibromyalgia. The reporter did not know of the patient's fibromyalgia before that point. The reporter stated that he and his lady friend, the patient, went to get the second dose of the Covid-19 vaccine on 01Apr2021. The reporter stated that on the day that the patient went to get her Covid-19 vaccine, the patient could barely walk. It was a chore for the patient to put one foot in front of the other. All the way in and all the way out of the vaccination facility, he had to hold the patient's arm to stabilize her and carry the patient's pocketbook for her. The reporter stated that the patient was in terrible shape. The patient ached all the time. The reporter stated that the patient may get a little relief for a few days and then the aches will come back for a week. The patient call these the achies. The patient's aches could really get bad, and that on 01Apr2021 when the patient got the second dose of the Covid-19 vaccine, the patient had the worst day. The patient got the second dose of the Covid-19 vaccine, came home, and everything was fine. Since the patient received the second dose of the Covid-19 vaccine on 01Apr2021, the patient had been a different person. The patient's achies were gone after receiving the second dose of the Covid-19 vaccine on 01Apr2021. The patient was real sparkly in her eyes since receiving the second dose of the Covid-19 vaccine on 01Apr2021. The reporter stated that he haven't seen the sparkle in the patient's eyes in years but he had seen it every day since 01Apr2021. The reporter asked the patient on 02Apr2021 how she was feeling, and the patient reported that she felt fine. The patient was sitting on the couch, 05Apr2021, with one leg on the floor and one leg tucked underneath her. The reporter stated that he haven't seen the patient do that in years. When the patient left the house that morning, 06Apr2021, the patient was being funny on her way out and was doing a dance with her feet and a move with her arms. The reporter stated that he haven't seen the patient do that in years and had been a totally different person. The patient has had nothing but positive results from the Covid-19 vaccine if that's what it was. The reporter stated that he normally couldn't get the patient to go anywhere or do anything. The patient normally stayed on the couch all day long. The reporter stated that the patient had some mental issues too, was depressed a lot and that the patient drank some too, because she never felt well. The reporter stated that the patient had been showing him 2 to 3 times per day that she could put her hand above her shoulders. The patient had to be careful because she had arthritis and when you get the bone on bone thing it could be bad. The patient went to see a therapist about a year ago. The reporter stated that the he couldn't do anything about the patient's drinking. He tried to get the patient to go back to the therapist a couple of weeks ago when things had gotten bad but the patient was unable to go because the therapist had shut down because of Covid-19. It just seemed that there must have been something in that shot that changed something inside of her. The patient had occasional good days but had never had 4 or 5 in a row. The patient had had really good days for her since receiving the Covid-19 vaccine on 01Apr2021. Time the vaccination was given as 9:15-9:30. No additional vaccines were administered.
