Hi Jeanne, I also have the band 24 hours a day. Mine is T4-T5 area. That is where my lesion is in my spinal cord. I also get a lot of tingling on the left side of that area. The grease line I was talking was actually a very greasy to the touch line . As the numbness was ascending so was the grease line. It was around my waist and moved upward until it stopped around T4-T5. Another strange thing I experienced was a few weeks in, I had to rub off a lot of dead skin on both legs. Very Weird! It doesn't sound like any one else had these things. Anybody have a problem with not sweating in affected areas? Linda in Pa
