My 17 Yr Old Girl Has Swollen Tonsils With Pus

My 17 yr old girl has swollen tonsils with pus looking stuff on them, bad headache, no energy and low to no fever. She had this about a month ago and took antibiotics and it got a little better, but has now come back with a vengeance. We went to doc on Wednesday and she is on antibiotic again, but is not getting better.
