My lymph nodes have been swollen for a while, but they don't hurt. I had seen a doctor and he gave me medication to cure a streptococcus. It worked for a few days, but it's now back. What should I do?

If the antibiotic prescribed by your doctor did not work and your symptoms have returned, it is important to consult your doctor again. They may need to evaluate if there is a resistance to the antibiotic, another infection present, or if further testing is needed to determine the cause of your swollen glands. Seeking medical advice and potentially getting a throat culture done could help provide a more accurate diagnosis and treatment plan.
