My scalp was still painful for a week, and I noticed a slight numbness in
my skin of my upper legs (top of thighs and bottom). The next day, the numbness
had spread to my torso area. Over the weekend, this numbness had spread to my fingers, hands and arms. My doctor checked out my reflexes (ok) and booked me for a blood test, to check for vitamin B12 deficiency, etc. 2 weeks later, the blood test results were normal. I am now waiting for a Neurologist appointment, which may take a while.
