Thank you for your reply.
I assume what I feel during the blockage is indeed the muscles strapped around my skull or maybe even the eustachian tube or anything related to the inner ear. However, what I do notice during it is an extreme decrease in cognitive ability, sometimes even physically. It goes as far as not being able to read, listen, think, feel etc... These symptoms occure after the tension of those muscles and the thing that is particularly obvious is the sound of the tensing and releasing of the muscles. Often times, also a feeling of some sort of liquid being released is feelable, which often comes hand in hand with a decrease of the bad cognitive symptoms. I know the brain has no sensors/receptors but this feeling may well be sensed by other parts of the skull. These liquids often times have a peculiar temperature, which makes them easier to feel it.
My neurologist said that it is unlikely that these are hallucinations. She said that it is physical, rather than psychological, although she did say that the actual "tensing" (physical) is caused by psychological reactions.
These psychological reactions are caused by attempts to suppress my tics as I have tourette syndrome. By doing this long term, I have learned that it's possible to suppress tics for long periods of time, but the effects are horrible to say the least. Basically, when I relax, the muscles relax aswell, but that's also when I get the tics. And due to social fear, I am suppressing them every minute of the day.
The release of the liquid is felt the most when I tic after a long period of having suppressed them/tensed my muscles.
So my question is, having being in this state somewhat 24/7 for over a year, is it possible that it has caused permanent damage in any way? As far as my ability to function cognitively goes, there is a huge difference when comparing myself to 3-4 years ago (I'm 23 btw), even at moments when I am not having the tics at all.
