after a couple of years I figured out why voice is nasal and why my head gets stuffy at times and then iis ok at times over and over during each day. It is because of dysphagia. My swallowing is ok at times and not ok at times every day and when it iis not ok my sinuses don't drain. I become mouth breather and and get stuffy head. PSP nasal voice -riddle solved. Swallowing is impaired but no PEG yet. Anybody else notice this?
