She is in pain while taking Gabapentin. The patient has pain in her back especially and her back is such a mess. She would hate to see what pain would be like without Gabapentin.  The patient was on a different Parkinson's medication prior to Gabapentin. The patient has not received additional vaccines administered on the same date. The adverse events did not require emergency room nor physician office visit. The patient has no prior vaccination within 4 weeks. The patient experienced adverse events following flu vaccination couple years ago in her right arm. A few minutes after injection, she started feeling severe jaw pain. Pain went up her shoulder, into her neck and jaw. Her tongue and right side of her mouth inside went numb and has been like that since. She has been to a neurologist, had an MRI done, and the whole nine yards. The cause is unknown. After second COVID vaccine dose, a milder form of this occurred, but not as severe. She was sitting there waiting and started feeling jaw pain and tingling in her tongue. She had tingling on the right side and the pain subsided. The pain was very mild and not as severe, began 18Apr2021. Her tongue and mouth went back to her baseline numbness maybe 6 hours after the COVID Vaccine. The pain quickly stopped, probably within an hour of the COVID Vaccine. Her jaw was a little sore for an hour. Shooting pain her jaw lasted for five minutes and then stopped. Her body went back to it's baseline normal. Her tongue is already numb since experience with Flu shot. She can still use her tongue and it functions, but it 50% numb. Her body does weird things and she doesn't know what it is doing. She had the experience with the Flu shot five years ago. She has been to doctor's about it. Nothing is wrong. A couple nerves in her brain were looked at. The neurologist doesn't know what's wrong or caused it.   No follow-up attempts are possible. No further information is expected.
