I'm a 57-year-old female who has been experiencing cold symptoms for 3 weeks now... initially clear nasal discharge, post nasal drip & coughing. Once, during the 1st week, while coughing I had an incident of projectile vomiting. Just now (3rd week), this occurred again - coughing accompanied by an incident of projectile vomiting. For the most part, I don't feel unwell, it's just that the coughing is annoying & the unexpected vomiting is disconcerting.
