I have a history of bad tonsillitis. Since last 4 days I am having pain in my right tonsils. There is difficulty in swallowing from right side. Sometime back I consulted one of the ENTs, he prescribed me Taxim-O (for 5 days) and Zerodol P (3 days) and asked me to do gargles. Today is my 4th day of the dosage, there is still pain. Can I extend dosage of Taxim O if in case pain doesn't subside? Or what alternative I should choose? I dont have fever, no cough.
