Cold sores can be a nuisance, but they are usually not serious. They typically heal on their own within a few weeks.

Small, fluid-filled blisters

The most common symptom of a cold sore is the appearance of small, fluid-filled blisters on the lips and around the mouth.

  • Size: Cold sore blisters are typically small, ranging in size from 2 to 5 millimeters.
  • Shape: The blisters are often round or oval in shape.
  • Color: The blisters are typically clear or yellow in color.
  • Location: Cold sore blisters most commonly occur on the lips, but they can also appear on the nose, cheeks, or chin.

Cold sore blisters can be painful and tender. They may also cause itching, tingling, or burning sensations. The blisters typically rupture and crust over within a few days. The crusts eventually fall off, leaving behind pink or red skin that may be tender for a few weeks.

Red, swollen lips

In addition to the small, fluid-filled blisters, cold sores can also cause the lips to become red, swollen, and tender.

  • Redness: The lips may appear red or pink in color.
  • Swelling: The lips may be swollen and puffy.
  • Tenderness: The lips may be tender to the touch.
  • Cracking: The lips may also become dry and cracked.

The redness, swelling, and tenderness of the lips can be caused by the inflammation associated with the cold sore virus. The virus can also cause the skin around the lips to become dry and cracked. In some cases, the lips may also bleed.

Tingling or burning sensation

One of the early symptoms of a cold sore is often a tingling or burning sensation on the lips or around the mouth. This sensation can be mild or severe, and it may come and go.

  • Location: The tingling or burning sensation is typically felt on the lips, but it can also occur on the nose, cheeks, or chin.
  • Duration: The tingling or burning sensation can last for a few hours or days.
  • Intensity: The intensity of the sensation can vary from mild to severe.
  • Other symptoms: The tingling or burning sensation may be accompanied by other symptoms, such as itching, swelling, or redness.

The tingling or burning sensation is caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin. The virus can also cause the skin to become inflamed and irritated, which can lead to pain and discomfort.

Itching

Cold sores can also cause itching. The itching can be mild or severe, and it may come and go.

  • Location: The itching is typically felt on the lips, but it can also occur on the nose, cheeks, or chin.
  • Duration: The itching can last for a few hours or days.
  • Intensity: The intensity of the itching can vary from mild to severe.
  • Other symptoms: The itching may be accompanied by other symptoms, such as tingling, burning, swelling, or redness.

The itching is caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin. The virus can also cause the skin to become inflamed and irritated, which can lead to itching.

Fever

A fever is a body temperature that is higher than normal. A fever can be a sign of infection. In the case of cold sores, the fever is usually caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin.

A fever can also be a sign that the body is fighting off the infection. When the body is fighting an infection, it produces white blood cells to attack the virus or bacteria. These white blood cells release chemicals called pyrogens, which cause the body's temperature to rise.

A fever can also be a sign that the body is dehydrated. When the body is dehydrated, it cannot sweat properly. Sweating is one of the ways that the body cools down. If the body cannot sweat, it can lead to a fever.

A fever can also be a sign of other medical conditions, such as the flu or a urinary tract infection. If you have a fever, it is important to see a doctor to determine the cause and get treatment.

In the case of cold sores, the fever is usually mild and goes away within a few days. However, if the fever is high or lasts for more than a few days, it is important to see a doctor.

Swollen lymph nodes

Swollen lymph nodes are another common symptom of a cold sore. Lymph nodes are small, bean-shaped structures that are located throughout the body. They are part of the immune system and help to fight infection.

  • Location: The lymph nodes that are most commonly swollen with a cold sore are located in the neck, under the jaw, and behind the ears.
  • Size: The swollen lymph nodes may be small or large. They may also be tender to the touch.
  • Duration: The swollen lymph nodes typically go away within a few days.
  • Other symptoms: Swollen lymph nodes may be accompanied by other symptoms, such as fever, headache, and fatigue.

Swollen lymph nodes are a sign that the body is fighting an infection. In the case of a cold sore, the infection is caused by the herpes simplex virus (HSV). The swollen lymph nodes contain white blood cells that are fighting the virus.

Headache

Headaches are another common symptom of a cold sore. Headaches can be mild or severe, and they may come and go.

  • Location: Headaches can occur anywhere in the head, but they are most commonly felt in the forehead, temples, or back of the head.
  • Duration: Headaches can last for a few hours or days.
  • Intensity: Headaches can be mild, moderate, or severe.
  • Other symptoms: Headaches may be accompanied by other symptoms, such as fever, fatigue, and muscle aches.

Headaches are caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin. The virus can also cause the blood vessels in the head to swell, which can lead to pain.

Muscle aches

Muscle aches are another common symptom of a cold sore. Muscle aches can be mild or severe, and they may come and go.

Muscle aches are caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin. The virus can also cause inflammation in the muscles, which can lead to pain and stiffness.

Muscle aches can also be caused by the body's response to the infection. When the body is fighting an infection, it produces chemicals called cytokines. These cytokines can cause inflammation and pain in the muscles.

Muscle aches can also be a sign of other medical conditions, such as the flu or a urinary tract infection. If you have muscle aches, it is important to see a doctor to determine the cause and get treatment.

In the case of cold sores, the muscle aches are usually mild and go away within a few days. However, if the muscle aches are severe or last for more than a few days, it is important to see a doctor.

Loss of appetite

Loss of appetite is another common symptom of a cold sore. Loss of appetite can be mild or severe, and it may come and go.

Loss of appetite is caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin. The virus can also cause inflammation in the mouth and throat, which can make it painful to eat.

Loss of appetite can also be caused by the body's response to the infection. When the body is fighting an infection, it produces chemicals called cytokines. These cytokines can cause inflammation and pain in the body, which can lead to loss of appetite.

Loss of appetite can also be a sign of other medical conditions, such as the flu or a urinary tract infection. If you have loss of appetite, it is important to see a doctor to determine the cause and get treatment.

In the case of cold sores, the loss of appetite is usually mild and goes away within a few days. However, if the loss of appetite is severe or lasts for more than a few days, it is important to see a doctor.

Fatigue

Fatigue is another common symptom of a cold sore. Fatigue can be mild or severe, and it may come and go.

  • Causes: Fatigue is caused by the herpes simplex virus (HSV) attacking the nerve cells in the skin. The virus can also cause inflammation in the body, which can lead to fatigue.
  • Symptoms: Fatigue can cause feelings of tiredness, weakness, and lack of energy. It can also make it difficult to concentrate and focus.
  • Duration: Fatigue can last for a few days or weeks. In some cases, it may last for longer.
  • Treatment: There is no specific treatment for fatigue caused by a cold sore. However, there are things you can do to relieve the symptoms, such as getting plenty of rest, drinking plenty of fluids, and eating a healthy diet.
