Hello, Occasionally after exercising I experience an irritated sensation in my nose that is immediately followed by profuse nasal running (rhinorrhea) that lasts about 24 hours. I thought I had an allergy. When I described these symptoms to my neurologist, she said that it was nonallergic vasomotor rhinitis, an autonomic nervous system disorder that results from Parkinson's disease. Subsequently I found a few references on the internet that indicated that exercise and parasympathetic nervous system overstimulation are possible causes of vasomotor rhinitis. Has anyone else had a similar experience? Do you have suggestions for prevention? Phil Tompkins Amherst, Massachusetts age 63/dx 1990
