What can I do for a sore thrut?

Sore Throat. There are many causes of sore throats. If suddenly occurring, i would suspect a viral cause, especially if associated with sudden fever, headache, and cough. A sore that last for more than a few days is generally due to an irritation such as acid reflux or allergies. If you have fever, with swollen glands in your neck, suspect a bacterial cause. Tylenol (acetaminophen) or Motrin may help. Persists?See your doctor.
Drink,rest,pain med. Most sore throats will improve with simple measures: increase fluids, get plenty of rest and take a pain reliever. You may want to gargle with warm salt water several times daily: ¼ tsp. Salt to ½ cup water. Some people will use honey in tea. If you have any trouble breathing, increasing pain, pain on only one side, fever above 101, a lump in your neck or recurring sore throats c a doctor asap.
Many options. When a patient has a sore throat and it appears to be viral without any antibiotic needed -- the focus should be symptom relief and this includes the following: drink plenty of cold fluids, (not warm or hot tea- this will only increase swelling in spite of recommendations from commonly held wisdom), take anti inflammatory meds like advil, aleve, (naproxen) etc., eat soft nonspicy food and rest!
