Pins and needles pain after fracture surgery may be caused by sharp fracture ends, subcutaneous soft tissue bleeding, stimulation of the surrounding nerves and other factors. 1. Sharp fracture end: After the fracture, the broken end of the fracture may be sharp, thus stimulating the surrounding muscle soft tissue, the pin prick pain. 2. Subcutaneous soft tissue hemorrhage: After the fracture, the subcutaneous soft tissue will experience capillary rupture and bleeding, resulting in local ecchymosis. When the bruising is severe, it will stimulate the sensation of pins and needles. 3. Stimulation of the surrounding nerves: It is also possible that the fracture stimulates the peripheral nerves, resulting in nerve pain. This may be manifested as a pins and needles sensation or a burning sensation or a discharge-like pain. Fracture surgery early pinpoint pain is generally normal, but if it does not subside for a long time, it is recommended that patients go to the hospital for examination and treatment.
