i had this problem for 7 years, check your urine PH level you can get everything you need at a health store. and then i started taken sublingual B-12 with B-6 & folic acid. and buffer PH pills for the acid imblancement. and within 5 days it was gone no more mucus. one other thing i had to do , due too not having a gallblatter was to take DLC pills , for ten dollars u mite fine out your problem. hope this will help you.
I've had this problem for over 15 years my problem started after having panic attacks??? if that's what it was since then I have had trouble with continuous mucus in my throat, been to ent specialist when it first started I don't know how many times. I kinda gave up because I was getting tired of being treated like It was all in my mind and that I was nuts haven't felt100% maybe 60% well since. couldn't afford to keep trying different doctors . so I just live with my symptoms..
