Another home run from Dr GrossanBy way of background 25+ years ago I was referred to Dr Grossan. For the prior 5 years I had suffered from near continual sinus infections and congestion. . My work had me flying 2-4 days a week at 15,000 - 25,000 feet in un-pressurized aircraft and scuba diving on weekends. I had a near constant sinus infection and was a heavy user of decongestants and antibiotics.Within a few weeks I was using only the nasal irrigator and a few techniques he shared with me.Grossan's work with deep sea divers and pilots (along with the general public) paid huge dividends .During our conversations I learned that he worked with some of the North Sea divers doing saturation diving where clear sinuses were a matter of life and death.Highly recommended
