I steped on a nail and had a tetanus shot on a Thursday. Saturday night I noticed the lymph nodes around my neck, in front of my ear, were very swollen. Sunday morning, it almost looked like I had mumphs. My neck feels tight and a little tingly, and I feel a bit light headed and very tired. I am on antibiotic and my foot is much better. I don t think the swelling is related to an infection, could this be a reaction to the tetanus shot?
