Many diseases have overlapping symptoms, making if difficult and time-consuming to diagnose them. Unfortunately, in your case it sounds as though MS & Lupus symptoms are both present. Some rheumy's are very hesitant to dx lupus, as there are a multitude of other auto-immune diseases that have overlapping symptoms -- some rheumies dx mainly on bloodwork, while others will include symptoms if the bloodwork isn't quite conclusive. Unfortunately, both MS and Lupus are the dx of last resort, used only if nothing else fits. I would not be too concerned about
not having a proper dx --
What I would be concerned about
is not having anyone address the symptoms you are having. I don't know if a Canadian GP is allowed to treat your symptoms, but I do know that often dx is determined by how we react to different treatments. The tingling does sound like something a neurologist would be best for, the way you describe it doesn't quite match the lupus neuropathy.
Can your GP do a brain MRI & look for the most obvious signs of MS while you wait for the neuro appt? You might also check www.lupus.org
for more info.
Hope you feel better soon,
