Hello, my throat has been hurting for a few weeks, I sing but I have been careful and I've kept fairly silent. Could this be caused by acid reflux?

Singing with reflux. Reflux is a common cause of voice problems. Pills alone are not the cure. Must include diet, not eating before bedtime, elevating back of bed and others. You can purchase a wedge to elevate the head of your bed. A pillow for the neck will NOT work. See www.grossaninstitute for more suggestions.
