I had a sleep study done and was told "you have the worse sleep apnea that we have ever seen" Got the machine and the setting was so high that I felt like a leaf blower every time I opened my mouth. Could not get used to it so I returned it. While in the office to return the machine I hear them telling 2 other people that "they have the worse case they have ever seen!" Fast forward 3 years and I am passing out when I stand up and having equilibrium problems and not sleeping, sinus problems. I am sent to ENT Dr. who tells me I have to have another study and Use the machine. I tell him I cannot and he gets real angry & tells me that He Cant Help ME and cancels my next appt. SOO...I went to a chiropractor and guess what? All of the bones in my neck were out of place and locked up. A couple adjustments later I am sleeping thru the night. No equilibrium problems and if my sinus get stuffy or neck gets stiff back to the Chiro I GO!
