Seems my Neurologist had a change of heart, he has now told in reply to my Doctor - possible Sjogren's after telling me nothing and sorry he could not help he then seems to have changed his mind. I had asked about Sjogren's on both occasions and the first time he said that is what the blood tests where for and the second time I asked if it was a possibility and he said no. I have now had more blood tests - anti- ENA and dsDNA plus some others but not sure what they are. I do have a lot of sjogren's symptoms. I should have the results at the end of the week so will keep you all up to date. Thank you everyone for your replies I will know which way to go after my results have come back.
