I have all the signs of lupus sle but all tests have been negative except anticardiolipin igg was 1 point over normal so it said high also i have high creactive protein and sed rate for 6 years. I feel im having a flare of symptoms im getting a rash back on my legs and fingers also in my scalp i keep getting butterfly rash and hives from sunlight and now my urin smells like sulfur or ammonia and its brown like coke it feels like i need to still go but can t. Im drinking gatorade constantly and im swollen everywhere. My pcp said the last few times i was there my urine had protein and blood in it but the culture showed no infection. I have this every few weeks but no infection could the undiagnosed lupus be attacking my kidneys?
