Hi Glentaj thanks again for the information, I have been tested for sjogrens as for everything under the sun but nothing has shown up as to what is causing this, I have had very specialised blood tests done mri scans, emg, skin biopsy and the paper test in my eyes(can't remember what it is called) so do not know if there is much left to test, I will probably see my consultant on Wednesday when I am on the ward to get my Ivig I must ask him if it is idiopathic.
