Acid reflux?
Little more medical advice for you. Another vote for Omeprazole. That stuff really works. Not over the counter, you will need a prescription.
I had acid reflux and heartburn for years and by the time I was treated, I had a vallecular cyst growing in my throat. True to form I ignored it till it almost blocked my airway. Just about said goodnight that time. If you like emergency ambulance trips and ENT specialists, you would love this. Best see a doctor.
