I am also being tested for an autoimmune disease. I have had a rash on my neck that comes and goes (for over a year) and 3 months ago it started spreading all down my back, on my stomach and hip. The dermatologist took a biopsy and it came back as chronic hives. Since I have osteoarthritis, carpal tunnel, pain in all joints and lost my sense of smell, it could be Lupus. The last time I had too much sun exposure, the fluid in my joints got low and the pain was terrible. Still waiting on the results of bloodwork and urinalysis. I also live in the NW, and am happy to see sunny days. However, I agree with couchtater. Take care of your skin, keep the sun off it as much as you can. I didn't worry until I started developing basal cell carcinoma, and the last surgery was right under my eye continuing onto my cheek. I was lucky this time. The scar does not show because she cut it out in a way that blends with the natural lines in my face. I'm not pressing my luck anymore! Good luck with your diagnosis! Hope all goes well.
