Ok I have heard the back is not involved in lupus,howeverI have lower back aches from standing too long and the ache wraps around my hips into my stomach. It is also accompanied by burning/warmth & it kinda feels like cramps when you get your period only theres no cramping just the other symptoms associated w/it. I dont have it all the time but when my lupus is flarinf I notice it more. Anyone know what it could be or have you experienced it before? =/
