I am wondering if anyone has experienced something similar to my issue and suspected it might have been caused by the straps from their mask.
A couple months ago I was doing some paperwork at a desk and the muscles on both sides of my neck seized up severely and I was unable to rotate my head in either direction for a couple days. I have mostly returned to complete mobility.
I do have daily issues with weakness though. The sensation that the muscles are pushing my head down. Raising my head during these episodes I can feel tension in those muscles.
The only way I can see to eliminate the straps as the cause and the continuing cause is to stop using the mask and seeing if the situation improves. That I know is a dangerous course of action.
I don't believe that I have the straps to tight. I do suspect that I might be effecting a nerve that is causing the issue. But that also raises the question of why two nerves (each side of the neck) equally?
Any thoughts and suggestions are appreciated.
