Why does my throat hurt on one side?

Question

Accepted Answer

Whole-throat soreness is usually a cold virus working both sides equally; pain parked on one side points to something more local. The most common local cause is tonsillitis, where one or both tonsils turn red, swollen, and sore - the NHS lists the pattern: problems swallowing, a high temperature, earache on the same side, swollen painful glands in your neck, headache, and tiredness. Tonsillitis is usually viral and settles on its own, but it can be bacterial (strep throat), which is where antibiotics come in. The complication to know by name is quinsy, an abscess between the tonsil and the throat wall. It is rare, but the NHS is blunt about it: a severe one-sided sore throat that is quickly getting worse, with difficulty swallowing or dribbling, needs 999 or A&E - not tomorrow, now. Gentler one-sided culprits exist too: a mouth ulcer on one tonsil, a wisdom tooth coming through, post-nasal drip pooling on one side when you sleep on it, or a strained throat muscle. A canker or gland cause usually announces itself within a few days and fades within a week. The NHS lines for any sore throat: see a GP if it lasts over a week, keeps coming back, or comes with a lump in your mouth or neck, or a mouth ulcer lasting more than 3 weeks.
