What Causes Pins And Needles?

Pinched Nerve

An individual experiencing a pins and needles sensation may have a pinched nerve. Bones, bone spurs, muscles, tendons, cartilage, and other connective tissues can all inappropriately apply pressure to neighboring sensory nerves. Trauma and a number of conditions can result in a pinched nerve. Carpal tunnel syndrome can cause paresthesia in the affected individual's hand. The main nerve that feeds into the hands passes through a ring formed by the wrist bones. The movements that cause carpal tunnel syndrome result in an inflammatory response in the tendons and surrounding membranes in the wrist. This swelling and inflammation narrow the amount of space in the wrist ring where the main nerve runs through, which pinches or compresses it. Sciatica is a condition characterized by a pinched sciatic nerve that feeds the legs and feet. Issues in the buttock, pelvic, and lower back area can cause this nerve to become pinched. Sometimes the large piriformis muscle in the buttocks can pinch or constrict the sciatic nerve, which interrupts nerve signals to the legs and feet. When a nerve is being pinched by other tissues, the impulses are unable to pass completely or at all, resulting in paresthesia.
