Tetanus can cause muscle pain. The main symptoms of a tetanus attack include sudden onset, impaired consciousness, frothing at the mouth, limb convulsions, body stiffness, presenting in an opisthotonos posture, and concurrent incontinence of urine and feces, with the duration varying according to the condition. Because convulsions cause the muscles to be in a state of rigidity, this leads to muscle ischemia and hypoxia, thereby increasing lactic acid and causing this state of muscle pain. Therefore, during a tetanus attack, measures should be taken to control these convulsions. At the same time, use chopsticks to prop against the teeth to prevent biting the tongue and other such incidents. If the condition is severe, immediately call emergency services (120) to get to a hospital for urgent treatment.
