First, the fracture is caused by the bone debris stimulating the surrounding tissue nerves, which can be detected in time by taking a film and removing it surgically to eliminate the sensation. This is a normal phenomenon and can be treated later to repair the nerve system and the sensation will disappear. In addition, at the later stage of fracture treatment, as the nerve system starts to repair, the growth of nerve synapses may cause a pins and needles sensation. It is usually mild and not particularly uncomfortable for the patient. In conclusion, whether the pins-and-needles sensation is normal or abnormal after a fracture, you should go to the hospital for prompt examination and treatment.
