She got her vaccine. when she went to bed around 10:00 PM that night she had severe, severe chills.  She was so cold that she could not get warm.  She got up and put on leggings on, a fleece on, a wool blanket and a down comforter and was still freezing.  It scared her as she got a vaccine and filled out a questionnaire and asked if she had another vaccine in the past 4 weeks and she answered yes.  She was laying there shaking like a leaf and looked back and got nervous as she thought she had her last COVID booster a week or two before that.  She called her doctor due to this who was not available and got a doctor on call who spoke with her, and asked her if she had a fever as she did not take the temp she couldn't answer that and lives alone and did not take it.  He told her to put more blankets on and stay warm and call back if she needed to.  She woke up at 4:00 AM and got out of bed and could barely stand up and using furniture to get to the bathroom.  She was hanging onto everything and was extremely not at that point to the point that she was stripping off her clothes.  She then felt nauseous and did not vomit, but did feel nauseous.  She got back up and hung onto everything and got the thermometer and it was 100.6, and made it back to bed and got in bed.  She called the doctor back and told him the temp, she asked if she had the flu, and said that he felt like that is what she had as he has not had a patient who has had a reaction to Prevnar 20.  He then told her in the morning if she was not dizzy and was able to drive and to go to urgent care and get a test for the flu to see if she had that.  She went to the urgent care the next morning around 11:00 as she felt like she could drive herself.  She got the test for the flu and it came back negative.  That lead him to believe it was a reaction from the vaccine, who was surprised she had a reaction from the vaccine.     Then on Wednesday she drove out of town for Christmas and went to her car to unload it, and leaned down on her left elbow to get stuff out and her arm completely gave out and was rolling on the floor of the backseat of her car.  That night she was playing a game with her grandson and she turned around and when she did that she put her left leg first to turn around and she fell on the floor as her leg completely gave out.  It was like her whole left side was affected.  She does not remember when the next time was, but her leg gave out again.  Ever since that happened she has been feeling really jittery inside, like a feeling that her blood sugar got really low, and wonders if it's from the vaccine or not.      The other thing that has happened her a few times she has had chest discomfort, which she has seen on the computer that if it lasts for more than 2-3 minutes to contact her doctor.  She does have a hiatal hernia and Barrett's esophagus and felt it was related to that.  The dizziness did go away the following day by the time she went to the urgent care.  Her leg has gone out on occasion, and a weakness in the left leg, but the arm has not given out.  She has not fallen down again but her balance seems to be off.    She had just had her physical and everything was normal prior to the vaccine.  She had blood work by her nephrologist a couple of months prior to that visit and all blood work was normal as well.
