pain
"I used Trixaicin HP for Thoracic Spine Damage to the nerve root at the C5, C6 level (C6 root) causing numbness in my index finger and thumb. I used gloves and put the Trixaicin directly on the pain. That caused the Trixaicin to heat up so much it burned. Not unbearably but it did cause me to wonder if it heated up worse on the pain because that was the most painful spot."
