Some words of encouragement I hope.
My Aunt had a closure about 18 months ago. Prior to the procedure she suffered from lack of breath and energy along with cold hands etc. Since the procedure she on top of the world, she now has none of problems she had before and is back walking, hiking and camping and certainly appears to be a lot fitter than she was.
Earlier this Year in May I myself suffered a TIA and am due to have my closure 19th Jan in London. I am 44, very active, I don't drink or smoke and I am vegetarian (boring hey!)
Although I do not suffer from the symptoms my Aunt had, her experience has left me with no doubt about the procedure and I am confident it is the right way to go.
All the best for the future.
