HI, my tonsils started hurting 2 days ago, and it is just the right tonsil, i have been taking paracetamol to get rid of the pain, which worked, until today- its hurting terribly every time i swallow, and Panadol has not worked. I used to have recurring sore throats and tonsillitis, and they would not hurt if i took paracetamol and it would disappear in about 2 days. Is this serious?
