I think we do suffer some similar symptoms and the one that no one else ever had is the total loss of long term memory! Mine came on after I had been in protracted withdrawal for 4 years ,so strange and it’s devastated me as not only does it take away my past,it tells me something happened to cause it and my neurologist is a waste of time as he has no answers plus he did 2 MRI’s ! Any info you can provide could help greatly. Head pressure and muscle tension of shoulder and back plus tinnitus round out my issues. Thanks for getting back to me and hope we can help each other!
