Hi Shrek ......I read your posts, and the one thing that I did not see - were MRIs....have you had any done. It took three MRIs before it became conclusive that I had MS. the first two did not show any, but then I went during times when I was feeling good, and the bod had a chance to repair the myelin - and with that did not show any lesions.
When I went for the last MRI, my hands were numb and tingling, and was experiencing the electric shock feeling when I bent my head forward. this time lesions did show up, it was quite plain and clear that I had MS...
I know what you are talking about when you say confusion, that brain fog feeling, extreme fatigue - etc....now that I look back I have had this for quite awhile, and I remember asking myself once - why am I so tired all of the time. When I get really tired, it feels like my whole body is shutting down - my head gets foggy, cant think straight, loose my cognitive skills, and my fingers seem to tingle more than ever.
I am fortunate enough that I can take breaks at work, and when i feel myself shutting down, I just close the office door, and close my eyes for awhile, sometime even nap!!!!! I nap instead of going for coffee in the morning and afternoon. this seems to eliminate that crushing - I can't think straight anymore" symptom. Fortunately for me, my job is very supportive, and allows me to have some down time - which is sooo great..
