My son was diagnosed with strep. He has been on amoxicillin for 5 days. He still has a fever, pus pockets, sore throat and now swollen lymph node on 1?

In brief: It happens

Strep is universally killed by the penicillin drugs, so that is still a good choice.
Lymph nodes often take a few days before they start swelling in response to an illness and take a few weeks to shrink after it clears.If he is continuing to run fever >101 after 5 days he is likely co-infected with a throat virus.If he is looking puny contact his doc for guidance.

He could also have other bacteria in his throat that are inactivating the amoxicillin. He could also be a strep carrier, for which antibiotics are not recommended (difficult to separate one from the other when symptomatic). He may benefit from a repeat throat swab.

In brief: Virus not strep

Did the doctor diagnose using a culture or rapid strep swab? Is he having fever above 101 F? Very unusual to have strep unresponsive to amoxicillin.
Sore throat may be due to virus instead of strep. Follow up with doctor for re-evaluation.
