 [ Symptoms ] i am 50 years old and in fairly good health should i have a pneumonia shot every year [ Disease ] well no that is certainly not a normal reaction to receiving a flu shot however it is possible the two events are unrelated regardless if the numbness and twitching do not clear up on their own after a few days this is worth getting checked out by a medical professional a number of conditions can cause the symptoms you describe a health care provider can diagnose the problem and get you appropriate treatment you might consider putting in a call to your primary health care provider for an appointment now because you can always cancel it later if the symptoms go away unless you are exhibiting signs of a stroke which would not include muscle twitches this probably is not an emergency situation hope this helps i had this as well i had the shot in my left shoulder yesterday and then the left side of my face went numb 5 hours later 24 hours later it still does not feel quite right doc is are stumped and want me to watch it think it may be a sensation reaction i get tingly on the left side of my tongue and random parts of my body occasionally no twitching or drooping of face muscles no more flu shots for this girl
