I Had no idea why this was shown on my discharge letter.
Regret to suggest that it is damage to the smallest strands in the brain.
The only route that I can suggest is consider whether your symptoms are Parkinsonian like.
I am now getting a lot of fatigue. Is it SF or not ? Hard to tell.
I too have gone backwards mobility wise. Walking now limited to a few hundred yards. Everything aches.
I had open heart surgery last year and trying to sort out which symptoms relate to which illness is impossible.
Keep smiling.
Think positively
Lots of us out here to support you
