Thanks Lynn, although I doubt very much if it is anything that I have done barring nagging him about taking tablets.
Tewcute yes I am somewhat relieved although I am fully aware that this is not going to be the end of it but I can always live in hope that the disease leaves him alone for a while.
Thanks for the tip Nanners, he is to have his regular blood screening on Tuesday due to the azathioprine and his consultant has asked for the vitamin D levels to be checked but even if they are ok and he is not 'officially' prescribed anymore I think it may be wise to buy them for him.
On another note. due to the large number of sufferers in the county where I live, the national uk charity that helps sufferers has now started a new group here which I have got involved with although it is still very early days in the formation.
