Thanks for the info. I have printed the article and sent it to the endo as he could not give an answer. Sometimes even Doctors don’t know which strenghens the fact we must never rely to much on them and question them at all times. This is something you could not do when I was growing up. A docs word was final then and you could not get hold of your notes. How much things have changed. It was actually noted in my notes several years ago!!

Thanks again.
