I have not been diagnosed with Lupus but my migraine specialist strongly suspects I may have it. She ordered tests last year and they all came up negative. I have investigated the symptoms of Lupus and I have so many of them I am struggling to see how I could not have it. I've had a lot of the symptoms since I was a child and some which have been more noticeable since I had my son. I was 35 when I had him and am now 57. I've been struggling on and off all this time. I stopped going to my GP because I felt like I was going mad with all the things that are wrong with me. Recently I have been back to my GP who has ordered more blood tests but I strongly suspect they will come up negative. My question is, could I have Lupus and yet it not show up in the blood test?
