For Patulous Eustachian
I didn't purchase the collar to prevent concussion. I bought it because due to Multiple Sclerosis and weight loss from Celiacs disease, I suffer from a complication called Patulous Eustachian. It's where the eustachian tubes do not open or close properly. This causes me to hear myself loudly, as if in a constant yawning state. I hear my breath, my heartbeat, etc. I'm a musician and singer, so it's difficult to play guitar or piano and sing while at the same time keeping on key. This collar has made performing a breeze! There aren't any guaranteed surgeries to help PET, and all treatments are usually unsuccessful. This collar has been an absolute lifesaver. I researched jugular compression and PET for many years before purchasing, and I couldn't be happier I did. I've recommend this collar to all of my PET forums.
