A 31-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration on 03Jan2021 at single dose in deltoid right for covid-19 immunization. There were no medical history or concomitant medications. The patient received the vaccine on 03Jan2021 and within 15 minutes had a generalized headache. Later that night she had generalized muscle weakness and pain, but really didn't think too much about it. The next day at work (04Jan2021), she had numbness on the right upper side of her lip and a pins and needle feeling in the right upper quadrant of the face. Had a lot of pain in the area as well on the right upper side of the face as well as a dull aching pain that lasted for hours. Later that day when using the computer and she was trying to reach for her mouse she noticed her right hand wasn't able to feel anything and that lasted about 20-25 minutes. Kept slapping the mouse with her hand, but could not feel anything, her hand went numb. Yesterday (05Jan2021), she had the same pins and needle feeling in the same area of the face and that dull achy feeling and it occurred for hours and it was very kind of debilitating for her at work.  Later that night she had pain in her right leg and felt the same way, that very severe achiness, which was the pins and needles feeling up and down the leg and underneath the right foot. All these symptoms tend to be on her right side and it definitely lasted for hours. It started about 1 and didn't end until 6-7pm. It even hurts to move the right eye in one direction and hurts to speak, the pain was so bad. This morning (06Jan2021) she had to call out of work because at 3am the generalized headache, pain was unbearable. She was still experiencing the pain in right leg and bottom sole of right foot. She did not receive any vaccines the same day or 4 weeks prior. No problems with vaccines in past. She had made an appointment with a neurologist and will have a MRI done on Friday, 08Jan2021.
