When an individual is affected by Lupus they are often times affected by something else too.
For instance, I have lupus but I also suffer from RA and Anemia. And a friend of mine too has Lupus but also suffers from Fibromyalgia as well. I can almost positively assure you that if you are diagnosed with Lupus, 9 times out of 10 you have another related condition and or disease as well.
Find anything familiar?
