Additional information: The patient had COVID and waited a month, she asked a pharmacist when she can get the vaccine and she said when you are feeling like yourself again and you are feeling ok so she waited a month and she felt fine no real crazy symptom or anything and she got the Pfizer vaccine and when she first got it, she got a little dizzy, little shaky and nauseous for about 3-7 minutes or so, so she sat there the whole 15 minutes and by the time 15 minutes was over she felt ok and she walked out. The patient was fine for 2 days and then she did get really fatigued and started feeling it and she was like okay and couple days later she started getting kind of dizzy like not like room is like really spinning but like just kind off balance and she had fatigue and then a couple days after that she got some muscle weakness in her right leg where she was kind of worried to drive but she could still use her leg okay. It just felt kind of tired like heavy it felt light like weird and couple days after that she had it in arm there is muscle weakness in right arm so all this kind of went off and on she had a good day like here and there where she felt ok this went to about a week and then 2nd week. The patient was chills like crazy too. She had chills in 4th and 5th day where she couldn't stop shaking and then the 2nd week the muscle weakness was about 2 days out of week it wasn't every single day it was kind of like 2-3 days out of week and then 3rd week and by the beginning of 3rd week she still didn't feel well. She was going to see a doctor and checked get out and see what he says.So she saw the doctor the Monday of her 3rd week and he put the patient on steroid and she was supposed to get 2nd dose that Saturday 5 days later he put the patient on steroid because she was scared of what side effect. She was getting into that was going to screw up. She got lot of tingling to nerve too tingling down legs. There were lots of shit going on anyway so he put her on for 6 days seems like it was helping. So she did not take the 2nd dose because she got too concerned. The patient didn't know what the hack is happening and she don't want to cause further bad symptoms, so she didn't take the 2nd dose and because she was on steroid (Treatment) anyway. The patient  couldn't take the 2nd dose and she was doing better it seems like she  was off the steroids now. The patient still getting a little dizziness here and there feeling kind of off balance. So what she want to know is she didn't know if there is something in the shot that didn't sit well with her and maybe she should not do it again or she don't know at this point what she was going to do. She didn't know if she should not take the shot again or try it again her doctor said if you want to try again go ahead but if you get those side effects again, just stop don't do anymore, so she don't know like, she don't know what is your advice on that.".
