[|Human|] I am a 42 year old male. I am a healthy adult. My blood work came back recently and it was normal, but I am experiencing some odd symptoms. For some days now I have been noticing my body twitch infrequently. It mostly happens when I am falling asleep, or relaxing, but sometimes it happens when I am wide awake. I have also noticed some sharp pains on the surface of my head. It only lasts a couple seconds. I cannot figure it out. It doesn t seem to be a serious problem, and it doesn t interfere with my daily activities, but I thought I would ask you anyways in case you have some insight and to stop it early.
[|AI|]  Hi, Oddly enough, twitches and pain on the head matter tremendously on where on the head they occur. At the back of the head is most common, and it is due to nerves in the top of the neck being affected. x-rays of the neck usually show the problem and a neck brace alone often helps, but surgery might be indicated. Twitches in the front of the head which people would say "face" are somewhat psychological and various nerve pills work. On top of the head is quite uncommon. Local nerve or skin problems might be the cause but frankly, I have never seen anyone with that problem. There are of course local nerve endings. They go in a short path into the brain. A brain scan might actually be indicated. Hope I have answered your query. Let me know if I can assist you further.
