A member asked:
After having an immunization shot, is it normal to have a knot in the injection site?
A doctor has provided 1 answer
Common finding: Most vaccines are given into the muscle underneath the skin and can cause a transient knot to form. This usually subsides in a few days to a week but occasionally persists for longer.It is not considered a sign of an allergic reaction.
