Dr. Sanjay Gupta’s on-line newsletter says yes. Forcefully blowing your nose can actually worsen your cold symptoms, says Dr. Peter Flip, a rhinologist and skull base surgeon at Rush University Medical Center in Chicago. Excessive nose blowing can cause a backward pressure of fluid draining from the sinuses. This could make an infection worse while also causing ear pain, headaches and nosebleeds.
One must, however, do a quick risk vs. reward analysis. If you’ve blown a giant snot-ball to leave as a message on the windshield of the jerk in the lot that parked to close or left his shopping cart behind your car, a slight headache or nosebleed seems inconsequential.
True justice comes at a price!
