Cold sores are common infections caused by the herpes simplex virus (HSV-1). It is characterized by an initial itching and tingling sensation, followed by blister appearances on the mouth and/or lips that will eventually pop and crust after a few days. These blisters may also form on the nose or cheeks.
Cold sores are highly contagious. This is why proper handwashing and avoidance of touching the affected area is important to halt the spread of the virus causing it.
The condition often doesn’t require treatment as it clears up on its own 7-10 days after symptoms appear. However, many doctors prescribe antiviral creams to help stop symptoms from getting worse.

Here is the progression of symptoms that will appear in a person with a cold sore:
Itching and Tingling Sensation
You will feel itching and tingling on the lips, mouth, cheek, or nose (depending on the infected area) at most two days before seeing a hard spot.
Development of Hard Spots
After a couple of days of getting the itchy and tingling sensations, you will notice a hard spot that feels painful when touched.
The hard spots you have will now become fluid-filled blisters.
Bursting and Oozing
Blisters will then burst and ooze fluid out of them. They will now turn into an open sore. This is the most contagious stage of the disease, so avoid touching the oozing blisters or perform thorough handwashing before and after touching them.
Your open sores will now start to crust, which is a sign that they are healing. You’ll notice temporary red marks on your skin, which will eventually fade in the future.
Now, if you contract the HSV-1 virus for the first time, the abovementioned symptoms may be accompanied by the following general discomforts:
Simply manage these symptoms like you would an ordinary fever: Get lots of rest, hydrate yourself, take an antipyretic medication such as ibuprofen or paracetamol, and do tepid sponge baths.
You may get a repeat episode of cold sores once you’ve caught the disease before. The onset, length, and time it takes to reoccur from the last episode varies greatly from person to person. It could reoccur monthly, yearly, or once every few years.
Reoccurrence is characterized by the same symptoms as the initial cold sore infection. The hard spots and blisters may form over the same areas where they used to be before. The sores will heal after a couple of weeks and will not cause any scarring anymore. The accompanying symptoms like fever, headache, and sore throat aren’t typically present during a reoccurrence.
There are certain triggering factors that may predispose you to get cold sores. These are the following:
Treatment for cold sores usually involves an antiviral cream directly applied to the affected areas. More severe cases warrant oral antiviral medications such as acyclovir. Patients usually respond well to these treatments, and their cold sores subside after around 10 days.
See a doctor if you still have symptoms beyond 10 days, if your sores become severely infected, or if the sores spread to areas other than your mouth, lips, nose, and cheeks.
