Pretty much everybody has experienced a headache at least once in their life. They are not usually something that concern us too much and we usually expect them to pass in a couple of hours or so. This makes it easy to overlook them, but sometimes you should really take notice. Headaches are a symptom of TSS, although the patient is also likely to be experiencing other symptoms that indicate the severity of the condition. If any headache appears to be too severe or if it raises suspicions in any other way, then you should speak with a doctor.
