I was given a pneumonia vaccine and a tetanus shot in same arm on Monday. Monday night I became ill with fever and chills. By last night fever was 102. Today it is finally back to normal. Hoever, my arm is still quite sore-- and just now there are 3 new lumps appearing to the side of the injection sites, almost look like insect bites (but aren t.) When I press on that area it s almost (not quite) as sore as the big swollen injection sites. Is this anything to worry about?
