How Long Can You Have An Abscess In Throat When Will This Abscess (tonsillitis Caused) Go Away?

When will this abscess (tonsillitis caused) go away? - how long can you have an abscess in throat

Two days ago, my neck is killing me, so I went to the doctor. I said I had tonsillitis and was given penicillin. There is no evidence to confirm the presence of the bacterium is not yet available. I already had an abscess on the tonsils, so I think that the visit was all that was necessary for the diagnosis of tonsillitis. I just take antibiotics for 40 hours and the abscess has deteriorated. My whole left pallatte is soft, white coating. It is very unpleasant. Besides, my throat is still killing. Should I go to the doctor, or should I wait?
