Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have sudden choking .Well there can be many reasons for symptoms you mention in query like foreign body entrapment, acid reflux, lump in throat and problems related to respiratory system . I would suggest you to consult ENT specialist once and get it examined. You should avoid hot, sharp and spicy foods. Take cough expectorants. You should take anti inflammatory medication such as Levocetrizine. You should use throat lozenges and go rinses with warm saline water. Take diet rich in vitamin B12. You should take antibiotics such as Levofloxacin or Azithromycin for 5-7 days. You should Chew a Vitamin C pellet. Take decongestants and mucolytic agents. Avoid cold carbonated beverages. You should get blood test done. You should get an x ray of the chest and pulmonary function tests done as well to know the exact extent of infection and can start treatment accordingly. Gargle with water rinses along with pinch of salt added in it. Sometimes the symptoms also occur due to allergic reaction. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
