hi. I was wondering what the priat trials are. is that the scs. spinal cord stimulator?? I know the pain pump. and personally I won't do that I think to risky same as the scs. but like most things it is a personal decision. I have always said that pain is a very personal thing. the most I would say. I would ask that you never lose hope hard as it gets sometimes but when it gets hard speak with some friends in the war. I know the pattern you have gone in . I am in a similar pattern. I went from crutches to cane to cane with walker. and the walker turns into a wheel chair for when i can no longer stand on my own two feet. thankfully that usage is minimal.(for now) remember to always hope high. its ok. even if you are let down. I usually hope high and plan for the worst so my feet are close to the ground if I fall from my high hopes.doesnt always work but its how I can keep convincing myself to keep high hopes. god speed my friend with many soft hugs and remember when your high hopes let you down you aren't alone , we can help you back up again..
