What are some home remedies for a sore throat? The left side of my throat feels like little sharp knives every time I swallow. It's been 3 days now

Sharp throat pain. First of all, please make a doctor's appointment to be sure you do not need antibiotics for a streptococcal tonsillitis infection. "Sharp knives" seems a very apt description of strep throat pain. If also with fever, swollen lymph nodes, headache, nausea, and rash, please be seen by a doctor ASAP for treatment. Warm salt water gargles and chloroseptic spray, tea with honey and lemon help to soothe.
