Symptoms
Acid reflux symptoms may include a cough, hoarseness, changes in the voice, chronic earache and sinusitis. Pain in the upper abdomen and chest and occasional heartburn are common. Symptoms of feeling sick, having an acidic taste in the mouth, a bloated feeling, belching and a burning pain on swallowing are also associated with acid reflux. GERD (acid reflux) if left untreated can lead to oesophageal ulcers and in severe worst cases could possibly even lead to oesophageal cancer.
