He did not have many other tests done ,not bloods, just one and it came back normal, so that is a good sign, still puzzling though as he certainly has not been feeling that well, let us hope we can find out what is the problem, knowing him he will be satisfied with the results and leave it now,whereas i think we should investigate further to find out what is causing how he feels. Thanks everyone for listening and your kind responses, a worry shared is a worry halfed lol.
