I have very bad acid reflux, a hiatal hernia, and Sarcoidosis. Right now, I am taking Prevacid 30mg. My voice at times is hoarse, so I went to an ENT dr. and he sent me for a test to look into my throat, and I was told that I have swollen vocal cords, and the acid is still backing up. I took Prilosec OTC but it did not agree with me. I have rashes on my knees, elbows, back and my neck and back and head hurt, Is the Prevacid enough and could it be causing all these symptoms?
