What is the Difference Between Ulcer and Cold Sore?
🆚 Go to Comparative Table 🆚The main difference between a cold sore and a canker sore lies in their location, appearance, and causative factors. Here are the key differences:
- Location: Cold sores typically develop on or around the lips, while canker sores occur inside the mouth, such as on the inside of the cheeks, lips, or tongue.
- Appearance: Cold sores are fluid-filled blisters that can become cloudy or appear as a white bump on the lip, while canker sores are usually smaller, gray or white spots.
- Causes: Cold sores are caused by the herpes simplex virus (usually type 1, or HSV-1), a contagious virus. On the other hand, the exact cause of canker sores is not well understood, but they may be triggered by factors such as certain foods, stress, or hormonal fluctuations.
- Contagiousness: Cold sores are highly contagious, while canker sores are not.
- Symptoms: Both cold sores and canker sores can be painful, but their symptoms may differ. Cold sore symptoms can include tingling or burning sensations, fever, and swollen lymph nodes. Canker sore symptoms may include a tingling or burning sensation inside the mouth, swollen lymph nodes, fever, and feeling physically unwell or sluggish.
- Treatment: While there is no cure for cold sores, antiviral pills and creams can help sores heal quicker and may reduce future outbreaks. Canker sores usually heal on their own within a week or two, but if they persist or worsen, a healthcare professional should be consulted.
