For 2 months I also have thick mucus in my throat, esp bad in the morning. I spit it out, mucus is clear or white. I do not have a cold, cough or nasal congestion. I use a netti pot and nasal spray in case allergies are the cause. Doesn’t really help, but after drinking lots of water, mucus thins and I can swallow although always lump in my throat. From my symptoms it sounds like a post nasal drip. Never had this problem before. Was wondering if the omeprazole I am taking every day could be the cause. I do have GERD which is why I take omeprazole. I really don’t understand why this started 2 months ago but that is when I started on omeprazole every day. Have appt with ENT soon.
