I had a head injury and post concussion syndrome in 2015, then was subsequently injured by psychotropic meds and an off label antipsychotic prescribed for severe insomnia and anxiety after. This caused a serious injury and adverse effect, and I now have a permanent neurological involuntary movement disorder called tardive dyskinesia that is a bit like Tourette's and Parkinson's disease combined. It's horrid.
I'm currently sitting here feeling very odd, with the feeling of what is called preminatory urges - the sensation of really wanting to sneeze or yawn (a kind of build up of pressure inside), except that I can't "tic" like people with Tourette's do to release the feeling. This is a common symptom that Tourette's patients have and it is also something that is part of disorders involving dopamine dysfunction.
This is just one thing I have among many other neurological symptoms which will probably never go away. I have accepted having to live with it up to a point, but it's at times like this with this awful sensation that doesn't go away that I literally despise my brain. It's just broken and can't ever be fixed 😪
