Thanks Kat. I have mixed feelings about trying anything new. No treatment will cure this, it just extends life if it works and doesn't cause any more damage. What's the point of extending a life of lying in bed all day and, on a good day, going for a 10 minute walk with a walker and physio staff. Why prolong that? But, it's not my life nor my decision to make, it's Dad's. Who can say what quality of life is for another.
