This sounds consistent with neuropathy, Marcia, and this tends to come and go with lupus. It is worthwhile to ask your doctor to check your vitamin B12 levels, blood sugar, and thyroid function to ensure there's no other treatable cause. For those of us over age 50, a blood test called SPEP can also be helpful.
Thank you Henry
OMG, this happens all the time in both my legs. 😳
