I have a swollen throat what should i do?

Depends on details: Doctor can examine. Throat symptoms often are from a strep throat infection (antibiotics are needed), a cold or flu (antibiotics usually not used), or from some other cause such as allergies, irritants, or stomach acid reflux. Usually, a person sees the doctor if throat symptoms are bothersome, recurrent, or don't go away quickly. Rapid mouth, tongue, or throat swelling is a "call 911" emergency.

Some basics: You can sit back & hope it is viral & will self heal. Throat sprays/lozenges help with the pain. You can go in & see if it is strep A & requires antibiotic treatment. The cited risk of not treating a strep is 1/200 for developing rheumatic fever & associated heart/kidney or brain complications. The risk to others depends on what it is but expect it to be contagious. What you do is up to you.

Choking?: If you have any trouble breathing or swallowing, rush to the ER immediately. If not, wait a few days and see if this will go away or improve. I presume that has not been any soreness.

Get tested: For significant sore throat with swollen tonsils / lymph nodes – see physician & get a streph throat test. Consider tylenol (acetaminophen) or nonsteroidal anti-inflammatory medications. Saltwater gargles: mix 1 tsp salt in 8 oz warm water – gargle several times a day. Or gargle with aloe vera juice twice a day. Add honey & a small amt. Of lemon juice to chamomile tea. Try ginger tea.
