I haven't heard of that as a Lupus symptom -- doesn't mean it can't happen.
Are you taking any new meds? It could be a reaction to something.
Also itching is one symptom of irritated nerves, which sounds like a MS symptom to me.
Since it's been going on more than a week, I would definitely see your MS or Lupus Dr as soon as you can.
