Opininions please if you have time...Im copd. Just finished course clarithromycin causing as ever severe oral thrush. Also just finished steroids, prednisolone. I have sjorgrens syndrome dries out mouth throat eyes, also have omeprazole for h hernia/acid reflux. The burning in my oesophagus now is severe, causing real soreness of chest. Can thrush go right down the oesophagus and cause this awful burning pain?
