I am NOT a professional in any field but would liek to tell you that afew years ago I had the palsy thing. Then things got worse. about 2 years after the year of palsy stopped I had a burst brain aneurism. This was nasty as it was on the main artery, when they did a cerebral angiogram they found 2 more problematic aneurisms. Looking back at the last few years, after my surgery to fix the 2 main aneursims I think the palsy was a sign that something was wrong.
The palsy was on the right hand side where the aneurism that burst was.
I often wonder if a little further looking on the part of the doctor might have prevented the life threatening burst?. The palsy used to happen when I was under pressure or severe concentration.
