What Does it Mean?
Tingling in the hands is a neurological symptom generally associated with pressure on your nerves. For example, if you cross your legs too long, when you uncross them you may get a numb, tingling, pins and needles sensation. Or when you sleep on your arm and you feel tingling when you move it.
These are the more common instances of tingling in the hands that people will experience regularly over the course of their lives. However, tingling in the hands can also be caused by trauma and injury as a result of nerve damage. This can be an indication of more serious damage to the nerves rather than merely pressure.
