Flu Shot Symptoms
Reviewed: Dr. Mera
1. Sore Arm
Among the most common symptoms of a flu shot is that, when given as an injection, the patients arm is likely to be quite sore for a while afterward. This is nothing to be concerned about and the pain will pass with no harm done. Not everybody develops this symptom and, for those that do, it will likely only last for a day or two.
The arm is also quite likely to become red and swollen at the location of the injection. These symptoms are a good sign because it shows that the body is reacting to the vaccine as it is supposed to.
