Cold sores, more commonly known as fever blisters, are a group of painful blisters caused by the Herpes Simplex Virus or HSV. HSV 1 type is responsible for causing most cold sores. These sores generally appear around your lip or in your mouth. They can turn up separately or in clusters mostly. Even though people don’t usually fall sick, the painful infection can leave you feeling ill for a few days.

Symptoms of cold sores
The symptoms of cold sores vary since they depend on the first outbreak or recurrence. If exposed to the virus for the first time, you may not have any symptoms for up to 20 days. These sores can last a few days, but the blisters may take up to 3 weeks to heal completely.

However, some common cold sore symptoms are as follows –

Tingling and itching sensation
Upon contracting this infection, you will experience a burning or tingling sensation in and around your lips for a few days. After that, small round painful spots start appearing, and blisters form.

Blisters
The blisters are nothing but fluid-filled small spots collected on the border of your lips. You may also find them on the tip of the nose or inside your mouth.

Oozing and crusting
These tiny blisters may sometimes merge and finally burst. The sores will be shallow and open for oozing and crusting over gradually.

An affected person may experience other complications such as fever, painful gums, sore throat, headache, muscle aches, etc.

Treatment options
The cold sore has no treatment option. Once the virus enters your body, it stays there for a few days. You can take steps to ensure the condition won’t aggravate. If you consult a medical professional, they will tell you to follow certain meal plans and avoid some food categories to combat this infection.

Foods rich in L-Arginine
Medical professionals often suggest that patients avoid foods that are rich in L-Arginine. It can worsen your cold sores in no time.

Some L-arginine-based food options are poultry, sunflower seeds, nuts, soy, beans, and others.

Processed food
