Hello, You have inflammation and should schedule a visit with your physician to check for strep. A simple swab can help determine a diagnosis. Treatment is a prescription antibiotic, rinsing with warm salt water and avoiding irritants. You want to take the correct antibiotic only after you confirmed a diagnosis. Make sure you drink water to keep well hydrated. Monitor for a fever since you report being close to people having the flu. Antiinflammatory medication such as Tylenol or Motrin may help reduce swelling and soreness. A viral source will need time to run through your body . Avoid close contact with others. Wash your hands often. Thank you for your inquiry. I hope you feel better and do not develop the flu.
