<p>You need to see a gastroenterologist and perhaps have an endoscopy. Acid reflux can cause damage to your esophagus. I didn’t realize I had it until I was rushed to the hospital thinking I was having a heart attack because of the shortness of breath and pain in my chest. I have been taking prescription meds since and the problem has greatly abated. I don’t know if it can damage your voice because I don’t sing but it can be very painful.</p>
<p>Please take care of it asap. OTC meds may only mask the symptoms.</p>
