hi my son had swollen neck lymph nodes five years ago and they got that bad they pushed his jaw out.he ended up on intrevenus antibiotics and they went down and to this day we didnt know what caused it,we were told they react like that when the body is fighting an infection.hope your ok and they go down.x
swollen lymph nodes are a common sign of infection, especially if the antibiotics are helping with the swelling, though swollen lymph nodes can also be a sign of lymphoma,
please get a second opinion.
