Strange sensation in foot

[Sheila__0]

  I am posting one more question regarding my husband - he hit his head in Sept, 97, has numerous problems remaining including tinnitus, ataxia, and other things.  He has a suspected kink in the blood vessels near his left ear.  Today he asked me how the circulatory system works, because now his right foot feels like its humming.  He said it was NOT asleep, but had what he felt to be vibrations or electrical impulses through his foot.  I could actually feel the movements, and they were not pulsatile, but random and spasmodic.  It was only on the one side.  Since he has such a difficult history, he wanted to know if there could be any connection between the circulation in his foot and the circulation in his head.  I hope that doesn't sound too weird.  I appreciated your last response, this is a terrific forum.  (but probably my last post...)

Dear Sheila:
What you are describing is known as fasciculations. These are abnormal
jerky movements in muscles that can be caused by many different things.
This is likely related to peripheral nerve damage/healing and results
in abnormal electrical activity that leads to this movement. The origin
of the damage to the nerve that is involved could very well be from a
circulation problem but this is definitely not related to the circulation
in his brain.
I hope this helps!
Good Luck!
