I am lupus patient. i am facing lower back pain problem and shivering leg for few last days. ?

Not usually lupus: The symptoms you are having are not common in lupus. I would recommend looking at other possible causes instead of blaming it on lupus

Lumbar Disc Disease: Common things occur commonly and low back pain with neuropathic symptoms in a 24 year old female are statistically more likely to be the result of L5 or S1 nerve root compression from a herniated disc. You may be at high risk if you are obese. Medications prescribed for SLE, including prednisone and antidepressants often cause weight gain. I urge you to seek MD or chiropractor and X-ray imaging.
