How can i get rid of long sort throat? what should i do?

Various treatments.: Without an actual examination, I cannot give specific medical advice on your particular health, but here is some good general information. Bacterial infection(strep throat) is helped by antibiotics. Allergic, viral, traumatic or other irritations won't be helped by them. Cold foods, soothing foods and/or anti-inflammatories can help in those other cases. (think smoothies).
