Sudden tingling pain in the buttocks may be caused by the following reasons: 1. It may be caused by muscle spasm in the buttocks, which is seen when the patient’s buttocks are cold or have a continuous bad posture. This can be caused by the spasm of the muscles in this area, such as the pear-shaped muscle and the gluteus medius muscle, leading to the symptoms mentioned above. 2. It may be caused by peripheral nerve lesions, for example, when a lumbar disc herniation or sciatica attack occurs, due to the stimulation of the relevant nerves, there will be sudden radioactive pain here. 3. The pain may be caused by an infection in the buttocks, such as a pressure sore or subcutaneous cellulitis in the buttocks, which may cause sudden stabbing pain.
