I have a bacterial infection in my ears and throat/tonsils. I have gone to the urgent care clinic where they prescribed me amoxicillin. So my lymphos where swallow on both sides but now the swelling has gone down I can feel a mass right below my lymphos it's not skrinking after 2 days of treatment. It's just still there same size and everything. Is this something I should go to the er about? Or just give it some time?
