I don't know if the tingling sensation in your scar is related to Lupus or not. However, I have a 4" scar on my right hip from a hiking accident. When I am sick, or in a really bad flare, it gets bright red, it itches and I swear that it even swells up a bit. I never mentioned it to my doctor because I just wrote it off to one of those things that Lupus aggravates when it flares :?
I put ice on it when these events occur. Eventually, the sensations go away, the redness goes away and I forget about it (until it happens again).
Maybe someone will have answers for both you and I
Peace and Blessings
