Son is scared that he has gerd doctors say he has sinusitis but he's still scared what should i do? his symptoms are throat related mostly

Age of son?: Not sure about DX of sinusitis? Problem communicating with the doc? Mild to mod cases of gerd are usually responsive to otc acid reducers such as antacids, zantac, (ranitidine) omeprazole.. It's generally okay to try otc meds for a wk or two then you need to see a doc if no better - a different doc may provide a different perspective / approach.
