Hi, my daughter has swollen lymph nodes on the right side. She has a spot just in front of her ear and under her jaw. They are very hard and the one on her neck is large enough to see. I took her to an urgent care and the dr. said he didn't see any other signs of infection, but he gave her an antibiotic anyway. He said that if it didn't work, she would need to see another physician. It has been 4 days since she started the antibiotic. The pain is going away, but the lumps are still there. How long should I wait before contacting another doctor?
