Why do I get huge cold sores so often when my doctor says my immunity is fine?

I started taking lysine daily and got serious about sleep, and my outbreaks became a lot less frequent. Stress and exhaustion were my biggest triggers, so managing those made the real difference for me.

Sun sets mine off, so wearing a lip balm with spf every single day has been huge, especially since chapped lips always seemed to come right before a fever blister for me. It is such an easy habit that it is worth trying.

Normal bloodwork does not always tell the whole story with hsv flare ups, so I kept a simple diary of sleep, stress, and diet to find my patterns. Once I cut back on late nights and stayed hydrated, my lips calmed down a lot, and it might be worth chatting with your doctor about what you notice.

Really glad you shared this. What has helped me most is treating it as a prevention question rather than a treatment one. Track your own triggers for a few weeks, get ahead of the risky days, and protect the lip barrier before the sun, wind, or a bad night of sleep can set things off.
