Hi Sunny
How hard it must be to watch UR dad endure all the surgery and pain.
Back surgery is always a bit touch & go. I had the same procedure u describe. It was a life savor. I was always putting it off not realizing how dangerous to do so, till the surgeon showed me a short film of the surgery it really helped answer all my fears & questions.
We are prayerful that all will be well for UR dad.
