I am 37 years old and was diagonised with positive ANA when I was 22. My ANA is ALWAYS very high, 1:1650 generally but 1:2450 6 months ago. (I just had a test yesterday and am anxious to hear the new number.) I also have low thyroid, a high positive AST (liver), allergies and asthma. I am asked to return to the University of Michigan Hosipital every 6 months, but they have yet to find a diagonsis for me. The super high AST (530) is very strange because the ALT is normal and they usually elevate together. A liver biopsy showed nothing. I am always tired, my hair is thinning, and I have had joint pains for over 20 years with no swelling or redness. Xrays do show signs of arthritis and I have brisitis in my hips. They have tested me for everything under the sun and nothing. The doctor wants to put me on Plaquinal but I'm leary of it. Anyone experiencing anything similar or have any suggestions?
