Cold sores or fever blisters are tiny, painful or uncomfortable blisters that typically form on the lips, chin, cheeks, or nostrils. The Herpes Simplex Virus (HSV) is what causes them. HSV-1 is most often responsible for cold sores, while HSV-2 is the main cause of genital herpes. Although cold sores usually heal within two to four weeks without treatment, they can cause significant discomfort.
A cold sore generally has five stages: initial symptoms, progression, rupture, scabbing, and resolution. But which is the worst cold sores stage? Let’s take a closer look at each stage to find out.
Symptoms in Each Stage
Cold Sore Stage 1: Initial Symptoms
The first stage of a cold sore is characterized by tingling, itching, or burning around your mouth. You may also have swollen lymph nodes and feel generally unwell. These symptoms usually appear one to two days before the blister forms.
Cold Sore Stage 2: Progression
In this stage, the blister breaks through the skin and begins to fill with clear fluid. It’s usually at its largest and most painful during this phase. The sore may also ooze fluid and bleed. At this point, you’re still contagious, so it’s important to avoid contact with others. This stage typically lasts two to three days.
Cold Sore Stage 3: Rupture
The blister will eventually rupture and leak fluid onto the surrounding skin. As the fluid drains away, the blister will deflate and flatten. You may see yellow or white crusting on top of the sore at this point. The sore will also be less painful than it was in previous stages. This stage generally lasts three to four days.
Cold Sore Stage 4: Scabbing
As the blister continues to drain, it will form a hard scab over the sore. The scab will protect the wound as it heals and help prevent infection. It’s also when you’re most likely to experience itchiness and tenderness around the sore. This stage typically lasts six to seven days before the scab falls off and reveals the new skin beneath.
Cold Sore Stage 5: Resolution
At this point, all traces of the cold sore should be gone. However, some people may experience residual swelling or redness around the site of the former sore for up to 10 days after all other symptoms have resolved.
List of Factors That Can Make Some Stages Worse Than Others
Although each stage of a cold sore can be uncomfortable, there are certain factors that can make some stages worse than others. They include:
• A weakened immune system: People with weakened immune systems, including those who have HIV/AIDS or who are undergoing chemotherapy, may find that their cold sores take longer to heal.
• Exposure to the sun: Sun exposure can cause cold sores to flare up and stay for longer periods of time. It’s important to wear sunscreen and other protective clothing when outdoors.
• Stress: Stress can cause cold sores to become more severe or last for extended periods. Taking steps to manage stress can help reduce the severity and duration of cold sores.
• Poor nutrition: Eating a balanced diet and getting enough vitamins and minerals can help improve your body’s ability to fight off the virus that causes cold sores.
Which Stage is the Worst?
Everyone experiences cold sores differently, so there is no definitive answer to this question. However, some folks may find that certain stages are more difficult to deal with than others. For example, someone with sensitive skin may find that the crusting over process is extremely painful.
Others may find that watching their cold sore progress from a small blister to an open wound is disconcerting. And still, others might find that having a visible scab on their face makes them self-conscious and anxious.
So while there is no “correct” answer to this question, it’s important to remember that everyone’s experience with cold sores is unique. It’s best to talk to your doctor about which stages are the most difficult for you and what you can do to manage them.
When Should I See a Doctor?
While cold sores usually resolve on their own, there are certain circumstances in which it’s important to seek medical attention.
If Your Cold Sore is Unusually Large or Painful
Most cold sores are small and heal within two weeks without any medical intervention. However, if you have a cold sore that is larger or more painful than usual, it is worth seeing a doctor. They may prescribe antiviral medication to help speed up the healing process.
If You Develop a Fever or Experience Flu-Like Symptoms
A cold sore by itself is not usually serious. However, if it is accompanied by other symptoms like a fever or Flu-like symptoms, it could be indicative of a more serious illness. In this case, you should definitely see a doctor.
If The Sore Spreads to Other Areas of Your Face or Body
Cold sores usually appear on the lips, cheeks, or nose. If it begins to spread to other areas of your face or body, it could be indicative of a more serious infection. In such a case, you should see a doctor right away.
If Your Cold Sore Lasts Longer Than Two Weeks
Most cold sores heal within two weeks. If yours lasts longer than that, it could be indicative of a more serious underlying condition. So, it’s best to see a doctor.
If You Have a Weakened Immune System
If you have cancer, HIV/AIDS, or another condition that weakens your immune system, you should see a doctor as soon as possible whenever you develop any kind of infection—including a cold sore. These infections can progress quickly and become very serious in people with weakened immune systems.
Seeing a doctor can help determine the best course of treatment for your cold sore and can help reduce the risk of complications.
While a cold sore can be bothersome at any stage, some stages are worse than others—especially if you develop complications. It’s important to know when it’s time to seek medical attention, as some cases can be serious. You can also check our article on Cold Sores Vs Sun Blisters: What Is The Difference?
