i am not really good because english is not my first language. But i wanna leave my testimony somewhere and i can't find a room for that . To say that i order the neck comforter and i start reading the book. after only two days of treatments and 2 nights try to not sleep on the side with pillows i see a difference already. The doctors wants to make a surgery on me for hernia and i suffer since 2 years of pain all the time. I have a little bit arthrose in my neck and tens all the time since i start pre-menopauses. I work on a computer and i have a very bad posture. When i have the neck comforter on i can sing really. When i don't have it the air doesn't pass through enough sometimes and i jam. Funny i discover that today. And i still have this pain in my shoulder like (bursitisme) but it is really better during the day. At night it comes back I want to ask if i can make push ups with the neck comforter on. Or it's better not. because i try to apply, th exercices, the good posture and the treatments of tractioin with the neck comforter. You know i live like i have 100 pounds on my head no wonder ...... thanks doctor Hoe and i hope you get this Manon Sauriol From canada m-sauriol@videotron.ca
