Hello friends, I was curious to know what symptoms and such are serious enough to head to the Emergency room? I believe Lupus is causing my severe headaches upon waking, and I have a feeling that my kidneys are also being affected by Lupus because of the constant urge to urinate, pain, etc. I also smell like ammonia, which I have read is linked to kidney failure. I do believe the severe headaches are caused by lupus, but I wouldn't want to waste my time by going to the emergency room only to be sent right home. Thanks for reading & I look forward to hearing your responses. God Bless you all.
