Hello and welcome to e health forum.
From what it appears, your symptoms are probably due to either viral or streptococcal infection.
Such infections are usually benign, and subside within 7 to 10 days with conservative management with anti-inflammatory medications like advil or motrin. Cough âand throat irritation can be reduced with cough lozenges and vitamin C supplements.â
Difflam is a non-steroidal anti-inflammatory agent, used as a spray, provides quick and accurate relief for unreachable mouth ulcers, sore gums and sore throat.
In case, you do not find relief within 2 - 3 days, or if the symptoms worsen, you may need a course of antibiotics to hasten the recovery.
