It does sound bad, but so does golf/football/etc when you break it down. Hitting a ball with a stick for several miles.
its also a very personal thing. How can you recommend something with the list of side effects and complications that DBS has.
I was well 'drilled' in the procedure, the possibility of complications and how I should set my expectation level and i weighed them all up against seeing someone who had went through it, with where I was with my meds and future drug regimes and quality of life.
So I went ahead ( no more puns, I promise ). With fantastic results. I'm not perfect, my walking and talking are poor, it's not a cure, if something else arrives on the horizon, it can be removed.
Soz about the speed of response, youve probably had your DBS surgery by now, but feel free to pm me or reply, as you see fit.
