My daughter(15) was diagnosed with tonsilitis, pharyngitis and laryngitis on jan 5th 2011..Antibiotics (Penicillin) appeared to help but a few days after stopping them, throat very painful again. 2nd course of antibiotics did the same, but she never felt 100% and sore throat came back. Been back at doctors and her tonsils are huge and both glands in her neck are very swollen and very painful to touch. Temperature goes up 38 and down again on and off. Doc convinced it was glandular fever so took blood tests and also did throat swab. Results all satisfactory. Took her back today and doc is still convinced its glandular fever. Help please
