[|Human|] my son s arm went completely numb - not tingly but dead. When touched by the other hand, no feeling at all. Fingernails were normal, as well a temperature, but after about 5 min feeling came back as warmth spreading from shoulder to hand. Then hand felt ice cold for a while. He is 47, healthy e xcept for smoking
[|AI|]  Hello, I read carefully your query and understand your concern. The symptoms of your son seem to be related to a herniated disc in the neck. A herniated disk in your neck can cause numbness, weakness, and a tingling sensation in one arm. It can also cause radiating pain in the arm, neck, or shoulders. It can be treated with rest, heat and cold applications, and over-the-counter pain relievers. I suggest using Tylenol to relieve the symptoms. If symptoms continue, see a neurologist and get evaluated. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
