I was diagnosed with NERD (non erosive reflux disease) and have had a tight neck on right side, some soreness in throat on right side and phleghm in throat. I can tell it is when my allergies and acid reflux act up which my ENT said are interrelated.

My voice gets more scratchy throughout the day. I was scoped a year ago or so, continue to see the ENT weekly for allergy shots but was wondering if there could be some other cause down lower in my trachea...tumor?

Is it worth getting another test to see down further and what would it be?
