I am getting icy hot sensations on my torso. IT moves around but never goes below the waist. Been doing this for 90 days or so . I thought it was an allergic reaction to soap or shampoo or something. Changes everything i could think of. Read on internet could be beginning signs of MS. Are there other signs? Anyway it s a bit annoying but not overly interferring with business as usual. Could it be nerve related possible. Had a bulged disc in neck a few years ago that caused pain down arm but that subsided with therapy and has not come back yet. Possibly related? Thank you
