Your symptoms could be due to a post nasal drip, which can cause a chronic irritation in the throat
. This could be due to a sinus infection
, a cold or a chronic allergy. Also, repeated strep throat
infections are an indication for tonsillectomy, as the tonsils may harbor the infection which keeps flaring up, or they may develop new infections. Check with your doctor regarding this. If there are persistent patches in the mouth or throat, consult a dentist. Regards.
