I'm Not MH but my opinion for what it is worth is that after an accident I had lost felling in the last two fingers in my left hand. The Ciropractor I went to indicated that it was L-3 or 4. And that this is a common, upon many visits and inquirys about my health He indicated that .1 to 1 cm per year regrowth would occur depending on how damaged the nerves where.
I was not into alternative health at that time, from his initial manipulations and since cleansing, the condition total reversed itself in 9-10 months.
