⚠️ What Can Trigger an Outbreak?
Even if the virus is “sleeping,” certain situations can wake it up and cause a flare-up:
- Stress (mental or physical)
- Being sick (like catching a cold or having a fever)
- Low immunity
- Hormonal changes (such as during periods)
- Sun exposure (especially on the lips)
- Fatigue or lack of sleep
- Outbreaks usually appear as sores around the mouth, nose, chin, or cheeks.
👄 Signs to Watch For
Cold sores often give warning signs before showing up:
- Tingling, itching, or burning sensations
- Redness or swelling near the lips
- Then within 24–48 hours:
- Blisters appear, often in clusters
- They fill with fluid, burst, and form a crust
- Healing usually takes 2–4 weeks
- Starting treatment early can reduce symptoms and spread.
