11. I have been using the PMV regularly for a few weeks or more and now, all of a sudden, I cannot tolerate wearing it for as long as I once did. What does this mean?

If there has been a sudden change in your ability to tolerate the PMV, this could indicate a change in your medical status, or the presence of a blockage (e.g., scar tissue or narrowing) in the airway that needs to be evaluated by your doctor or a specialist such as an Ear, Nose and Throat Doctor (ENT or Otolaryngologist) or Lung Doctor (Pulmonologist) before you continue wearing the PMV.
