Ten Tetanus Symptoms to Watch Out For

8. Elevated Blood Pressure and Heartrate

Though muscular and nervous system problems cause most of the symptoms seen in a person with a tetanus infection, some people also experience elevated blood pressure and heart rate. Researchers believe these symptoms develop because of the way the bacterium affects the sympathetic nervous system, the same system that prompts the fight or flight response. When this system is triggered, the body is reacting to trauma and preparing its response, and these reactions require increases in heartbeat and blood flow.
