Symptoms Of Listeriosis (Listeria)

Headache

A headache is another symptom that can occur if the listeria infection spreads to the patient's nervous system. Like a stiff neck, patients should seek emergency medical treatment for a severe headache. Serious headaches are especially noticeable if individuals don't commonly experience tension headaches or migraines. They may feel like their head is throbbing, pounding, like there's a stabbing sensation behind their eyes, or like their skull is going to explode. Headaches may be accompanied by light sensitivity. When related to listeriosis, a serious headache indicates the infection has begun damaging the nervous system or increasing pressure in the skull. This means the patient needs to go to the emergency room.
