Hi. Im 21 yrs old. 6 days ago i woke up with a sore throat and red right tonsil i went to the local doctor he told me i have an infected tonsil(he didn't even check my throat) he just listened to my symptoms. He gave me antibiotics written DOXY After a day my whole throat was red including the left tonsil. Now after 6 day my tonsils look mashed and red. my neck is steef and heavy head(pressure like).
