Anytime your body contracts a virus, it does its best to fight it off - herpes is no different. As white blood cells try to attack the virus and antibodies form, you may feel like you have a headache, or experience muscle pain, even if you haven't done any exercise recently. As with many other health issues, your body will let you know if you have a "biological intruder" and if it's working to get rid of it - the best way to spot this symptom is to remain aware of the way you feel, rather than instinctively brushing it off or "explaining it away" with implausible causes. Take over-the-counter pain medication as needed, but be sure to note when and for how long you're experiencing symptoms like these, particularly in conjunction with other symptoms - a pattern can point to herpes.
