Hi thanks for choosing HCM,
Numbing of skin due to ice is called FROST BITE.
It is injury of that part due to ice and salt. Here salt will lower the temperature further down, result narrowing the blood vessels on that area and reducing blood circulation to produce numbness.
It is also one type of protective phenomena to divert the blood to vital organs to keep your body alive.
Treatment is Immediately remove the ICE from that part.
Rewarming that area by drencing that part into the tolerable heat water for some time.
Don't rub that part, it will produse blisters.
Thank you.
