My wife recently had an episode that resuted in a diagnosis of peripheral neuropathy. With that she had total nubness (if not paraysis) on the left side of her face and neck. As her symptoms (especially pain in hands and feet) have gotten better, she has had a ticklish cough throughout and it seems to be getting worse. She has coughing spells with clear mucus taht make her feel like she is suffocating. She also has tightness in her throst that gives her a feeling like she cannot swallow. Any ideas?
