Lupus Support Group
Lupus is an auto-immune disease in which the immune system cannot distinguish between threats (like viruses and bacteria), and healthy cells and tissue. As a result, the body produces antibodies that inflict cell damage, most commonly targeting joints, skin, kidneys and the nervous system. Join the group and find support for coping with lupus.
Now on to the possibility of lupus. Most laypeople don't realize that there are many illnesses that cause many of the symptoms that are associated with lupus. Lupus is called the Great Imposter, but it goes the other direction too. An RA panel will not test for what you need to check for lupus. For that, a doc needs to run an ANA tests, an anti-DS-dna, anti-SS-dna, and a complement level. (low is bad, high is still normal.) You don't mention your symptoms outside of a rash from being in the sun, but illnesses like porphyria also cause rashes in the sun. And sunburns for that matter can look like rashes.
If you want to be totally certain you can rule this out, then you need to go back to the doc and have the appropriate tests run. Also, go to the website for the Amer. College of Rheumatology and read the 11 criteria for having lupus. To be diagnosed, you need to have 4 or more items on the list. Some you won't know without lab work, but others (like oral lesions) you will and might not have associated with lupus.
Best of luck and I hope you DON'T have lupus and we don't see you again. [g]
