Hello. Ive had constant mucus/phlegm in my throat for a year and it has recently got worse. It occurs after drinking after liquid and can make me feel quite sick sometimes, It's driving me mad because when ever i drink anything i need to spit out/cough up loads of mucus. I've been to the doctor's and he doesnt think it's post nasal drip and im currently on a drug meant to treat acid reflux at the moment, but its not working.
