Strange you should post that, I had a "funny turn" just over a week ago and Mr Man thought I had had a mini stroke. The conclusion was that I had suffered some kind of "fit" but that it was nothing to worry about. I don't know, I never seem to get clear answers, but as long as it's followed by "it's nothing to worry about" then I suppose that's ok. Without doing tests, how can a medical professional tell if you have had a TIA or a fit? And is the latter really nothing to worry about? Oh, and I'm glad that your knee is getting better by the way :)
