i am male, 60 yrs of age. at annual checkup Thurs, i got DPT shot. today, saturday, the lymph node in the armpit on the side which got the shot is swollen (about 1/2 golf ball size) and tender to the touch. the muscle at site of injection is expectedly tender. i am assuming the swelling is related to the DPT. otherwise, no fatigue or temperature and feeling good.
