A 43-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot Number: EN6208, Expiry date: unknown), via an unspecified route of administration on 17Mar2021 (at the age of 43 years old) as dose 1, single for covid-19 immunisation. The patient medical history included menstruation on 31Mar2021 (I did start mensuration on the 31), injury from car accident from 2015 (I do suffer from an injury that I have been recovering took place 2015 that injury made my muscular skeletal system kind of little bit vulnerable). Concomitant medications included Vitamins, anti-inflammatory medication, and muscle relaxers from an unspecified date. The patient experienced mild sciatic pain in left leg 13 days after the first dose, sciatica; pain was so bad she wanted to go to the ER on 31Mar2021, she could not walk for good 2 weeks; she was limping, bottom of her left butt was like numb, fatigue, her right arm just like hurting on an unspecified date. The patient reported stating she developed an adverse reaction and its related to nervous system disorder, she received Pfizer vaccine on 17Mar2021 and then on Mar 30Mar2021 started to get mild sciatic pain in left leg, sciatica (nervous system disorder) and then the next day after that on 31st actually, the evening of 30th, the pain was so bad decided, rest at home. The patient already had some anti-inflammatory medication and muscle relaxers because she suffered from an injury that she has been recovering took place 2015 that injury made her muscular skeletal system kind of little bit vulnerable to like, high exercises, if patient does anything extreme, basically have to do things pretty slowly but during that time period that this happened patient was active she walks at least 30mins a day and up until that point patient was active where she was walking but because of this sciatic pain that just came on she wasn't able to walk for good 2 weeks so was being treated for right now and patient was taking something extra that she never taken before. The patient taking pain medication to get treated.

During her mensuration regularly all she got just cramp, don't develop any like excruciating pain or anything of sort, patient developed sciatic pain after 13 days after the first dose of the vaccine and on the 14th day it was debilitating. Being treated for sciatic right now it hasn't fully gone, able to walk but not able to walk like she did like patient was limping and then the bottom of her left butt was like numb so end up being treated for it but think it's worth.
