Hello, You had a sore throat, you used throat spray and gargle. It is better but you have a frothing sensation and swelling, feeling of something stuck in the throat. Such a symptom may commonly occur due to strep throat, allergy, sinus infection, common cold, globus pharynges, etc. You are suggested to gargle your throat with salt water three times a day. Take fluids and water so that your throat mucosa is not dry. Prefer to stay in a room that has humidifier. You should take liquid or semi solid food so that you do not hurt your throat mucosa. Avoid intake of caffeine and alcohol as it will irritate your throat mucosa. You are suggested to to take acetaminophen, one stat when needed. It will help to reduce pain, irritation, inflammation, etc. You can take Claritin D(loratadine and pseudoephedrine) and PPIs to help control the sensation of obstruction and frothing in the throat. However, you are suggested to get clinically examined by an ENT and get required investigations done so that ailment detected can be treated at the earliest. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
