Cold Sores

Cold sores are caused by herpes simplex virus and are contagious. Generally signs and symptoms of cold sores are seen after twenty days of exposure to the virus. Cold sores begin with tingling near the mouth, followed by a cluster of small, painful blisters; there may be fever, sore throat, or swollen lymph glands. These sores burst and crust over, but normally heal within about 10 days. Triggers such as colds and flu, fatigue, stress, menstruation, cold, wind, or strong sunshine can reactivate the virus, causing another cold sore.

Home Remedies

• As soon as you notice tingling, apply a small ice pack to the area, for about
     5-10 minutes every half hour.

• Apply tea tree oil onto a cold sore, which may help the blisters dry out and
     heal more quickly.

• Gently rub aloe vera gel on the sores.

• Place a cool, wet towel on the sores three times a day for 20 minutes each
     time to help reduce redness and swelling.

• Apply a tea bag for few minutes on the blisters, repeat this every hour.

Do's

• Wash your hands frequently to avoid spreading the virus.

• Eat lots of fruits and green leafy vegetables.

• Apply petroleum jelly to the affected area to prevent cracking or bleeding.

• If stress or fatigue are triggers, get plenty of sleep, and try breathing
     exercise.

Don’ts

• Don’t pick or squeeze sores.

• Avoid close contact and don’t share towels, cups, and glasses.

• Avoiding prolonged exposure of your lips to sunlight.

• Avoid tea, and coffee.
