I had it done by Mr. Vedi and haven't looked back since. All of the pain has gone and I'm back to running as if there had never been a problem....when just a couple of months ago it hurt to even walk.
Like the other posts, I wanted to avoid surgery and hence felt a bit strange going to hospital, but that was to get the injection guided in by ultrasound to make sure it went in the best place (apparently).
He's based near Rickmansworth (Bishops Wood hospital) and I thoroughly recommend him.
