HI I have gone through yuor mail and as you said that you had left sided tonsillitis about 15 days back and you have taken medicines for that later that gets cured as you have been told by your doctor. I would like to tell you that tonsillitis is a disease which usually involves both tonsils. Whenever there is unilateral tonsillitis there will be either associated cyst or stone called tonsilolith. these are having tendency for recurrence and giving rise to complication as paratonsillar abscess. Once paratonsillar abscess develops there occurs severe pain in throat radiate to ear and jaw.You are now advice to consult your E.N.T.specialist to do clinical examination and treatment.Thanks.
