ISC New York is always the road block. 3 days to travel from who knows where province China. Clear across the world to New York. Only to sit and Stevenage in ISC New York for sometimes upwards of 2 weeks.
If a toenail has completely fallen off, it can take up to 18 months for it to grow back. A toenail can take longer to grow back if the nail bed has permanent damage. In some cases, old nails do not completely fall off, and they act as a protective barrier to the nail bed until the new nail begins to grow.
It may just appear that the new nail is not reattaching. In his book, Nails: Therapy, Diagnosis, Surgery, Dr. Scher states that it takes the normal nail about two months to grow the 5 mm out from under the proximal nail fold. The replacement growth of injured nail is slightly faster.
