While their size and shape vary with location in the nervous system, most neurones contain the same parts: a cell body; a number of highly-branched outgrowths of the cell body called dendrites; a single, long nerve fibre (or axon) extending from the cell body; and branches at the end of the nerve fibre (axon terminals).
My doctor said that usually happens when blood pressure is high and you get that strange head sensation. But as I was reading some documents on net, I found out that it could also be some sort of a panic attack. You could try next time it happens to relax, try thinking on some peaceful place, and just calm down.
Hyper- or hypoventilation is another cause of tingling in head symptoms. When we breathe too shallowly and donât take in enough oxygen (hypoventilation), this causes the CO2 levels in the blood to drop, which can cause a tingling, tingly, pins and needles sensation anywhere on or in the body.
