Are there undetectable autoimmune deceased?

[Kutzner78]

30yo/f for the past 3 months I have been battling a severe headache and a rash that comes and goes. For the most part the rash is generalized to the legs. It is a non blanching rash of that helps. Also have had a low grade fever off and on. It started with headache, then fever, then rash. A couple weeks later I started getting joint soreness and weakness. That happens less freaquently now as does the rash. However the headaches are super persistent. Last week I was hospitalized because the headache was so bad and I developed numbness,burning,tingling in the right side. I have been tested for everything under the sun. Creatinine is with one normal limits but steadily rising, urea nitrogen is steadily rising and now outside normal limits and I have developed blood in the urine. I should also note that my doctor thinks I have a rare autoimmune disease that does not show up in testing but did not disclose the name only referred me to a nephrologist and rheumologist. Anyone have any insight?

A few things for your consideration:
- Gastro-intestinal bleeding (look into demulcent herbs)
-  Dehydration/low water intake
-  Poor circulation- impaired blood flow to the kidneys
(leading to reduced urea clearing)
- hypothyroidism ( one of the important yet not very known
functions of the thyroid is clearing of cellular debris in means of activating the enzymes responsible for this process)
- Antigens when they combine with antibodies form what is known as immune complexes, which can  cause kidney damage. Immune complex deposits on organs are linked to some autoimmune diseases such as Lupus and  Sjögren's syndrome.
Interesting observation which I copied from another reply of mine earlier today:
"While I'm here, something I should mention, is that when I had been studying Dr.Barnes work (one of the top thyroid doctors ever), one particular finding stayed with me.
From ALL the thousands of patients he treated for hypothyroidism (using natural desiccated thyroid ) NONE of these patients developed Lupus.
The ones who had been already diagnosed with Lupus, none developed any new signs of  of organ involvement, while being treated by Dr. Barnes for hypothyroidism (type 1 and type 2) "
- Chronic stress including hidden stress causing elevated Cortisol levels -but unsustainable in the long term- is also
a factor in high BUN values.
Hope this helps.
Please let me know if you need any details.
