Reading through all of these comments has at last made me realise I’m not alone in awful choking thick mucus in throat. Had COVID in December 2022 then developed post nasal drip. That has really become very thick and stayed white ie;not bacterial. OTC medications have not really helped nor sadly any prescribed nasal sprays steroid or antihistamine nor asthma treatments. Not aware of hiatus hernia problems. Some days I just can’t swallow or breathe easily, what does help a bit are sipping very hot cordials Even taking to sleeping propped up and have a thermos to take sips of hot cordial through the night as it’s keeping me awake anyway. Would a visit to ENT help? From England .
