One of my symptoms that I get during a relapse, and am currently having right now, is temperature sensation differences between the back side of my left butt/leg/foot, compared to the right. When I sit down on a toilet, or walk barefoot on a cold floor, I can feel the coldness with my right side, not my left. It started out small and has gradually made its way to my whole lower left side. But the weird thing about this symptom is that I still have feeling. I can pinch my leg/foot/butt and feel the pinch or scratch. It's just the sensation of hot or cold that is gone. I've had this two other times with relapses and each has resolved. I'm keeping my fingers crossed and just wanted to share this symptom to see if anyone else can relate? I'm also wondering if there's a scientific or medical term for this as well?
