I am going to see my endrocrinogist later this week but I want to know if anyone has experienced the tingiling and numbness only on the left top portion of there skull. If feels like what the dentist does before he drills on a tooth. The numbness comes and goes and doesn't seem to do so with any warning or any activity. I am a T1 Diabetic and take meds for that. Before I was on insulin, I did have numbness in my fingers and toes but this feels different than that.
