I recently went to a family get-together and there was a lot of smoking in a small area with little ventilation. I do not smoke. When I came home from this rendezvous my nose started bleeding.I noticed I had been somewhat congested prior to this incident. Think it was just seasonal allergies or coudl the cigarette smoke be the culprit?
I don’t know… but anything that irritates your nose to any significant degree could make it bleed.
