I hate it when doctors are so non-specific about what they are telling you. Is it because they just don't think you will be able to take it all in, or because they don't have the information themselves and are telling you something which is basically hearsay?
However, since many autoimmune diseases are showing themselves to be caused by an infection, it is not really surprising that many married couples have an autoimmune disease. In my case, I was genetically predisposed to develop MS and my husband fibromyalgia and atherosclerosis. They can both be caused by the same infection. I had MS when we married, with a reinfection of C Pn, my MS became aggressively progressive and my husband developed atherosclerosis and his fibromyalgia became so bad he might have been crippled within a few years had he not treated himself or died from coronary artery disease before that.
As a medical doctor himself, he was very good at ignoring what was wrong with him, but only when it became obvous that my MS could not be ignored, did he research what was now available and realise that the treatment being developed at Vanderbilt University just might work for him as well.
Carolew, we are both stubborn as well!
