I have been diagnosed with non allergic rhinitis and the sneezing and congestion happens mostly when I am ready for bed, or comes on suddenly during the night. At times I wake up because I am about to sneeze. I had a CAT scan, and my ENT doctor said my sinuses were inflamed. He gave me a 5 day steriod treatment and said he could only do it a couple times a year. I felt great for 3 weeks, now it's back to being as is was prior to the treatment. I have tried Veramyst and Ipratropium Bromide nasal sprays along with nasal flushing, all they do is bring on an attack. The sprays trigger it almost immediately and the irritation continues for up to an hour or more. It doesn't matter where I am, so I know it's not environmental. I sneeze on the average of 30-40 times through out the day with congestion. This started about 1-1/2 months after I quit smoking a little over 3 years ago. I am a healthy 49 year old female, 5 ft tall - 120 lbs. I workout 5 days a week, and eat a healthy diet. The only drugs I am on is Prempro for menopause, and levothyroxine for thyroid.
