On the right side her foot starts having a tingling sensation with shooting pain up the right foot. Her right foot experienced tingling feeling in the toes and ankle but it went away and it's better now. This really scared her, that happened just a few days ago. She did not go to the doctor for the reported events, but now it has gotten so serious, she is having to take time out of her life and pay for a neurologist to check this out due to the severity of her symptoms. She feels like her left side has gone lame, she can still use it but she is concerned about using her left hand at all if it gets worse. She stated this is very concerning she might lose complete ability in her left hand and arm.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202200221732 Same patient/ similar drug, different AE in seperate time gap;US-PFIZER INC-202200222074 Same patient/ similar drug, different AE in seperate time gap
