What are Cold Sores?
Sores are nothing but patches of broken ulcer-like skin. Cold sores in specific are blisters which are filled with fluid. These cold sores are also called fever blisters and are most painful. You will commonly find these cold sores in and around the lip area and mouth and to a lesser extent on the nose portion of the face.
Cold sores are filled with fluid and when they break open for some reason the fluid comes out and dries off within few days. The fluid is very active and contagious; however, it becomes less contagious as it begins to dry off. The breaking out of the fluid causes the spread of cold sores to other parts of the body as well. The normal healing time for cold sores without any medication is about 10-12 days.
Cold sores are caused by a virus which is known as Herpes simplex virus (HSV) which is of two types; type 1 and type 2. Usually, the HSV 1 is responsible for causing cold sores. Now we know that these sores are filled with fluid and when the sore breaks open the fluid causes the spread of fever blisters. When a healthy person comes in contact with this fluid, because of reasons like touching, kissing, contact with infected saliva etc. the virus transmission and spread of cold sores occur.
When a person comes in contact with the HSV it is very difficult to get rid of this organism. Even after the blisters have healed the virus stays in the body in a dormant form. This is the reason for recurrence of cold sores. However, it is not always necessary that the presence of HSV in the body will show symptoms. Some people do not get cold sores at all and the virus remains in their bodies in a dormant mode or sleep mode throughout life.
How Will I Confirm Whether I Have Cold Sores? What Are The Peculiarities?
The most common signs and symptoms are discussed below.
- Prodrome (pre-symptoms) – Sometimes you will observe a set of symptoms occurring before the development of cold sores. These symptoms are burning or a tingling kind of sensation a couple of days before the formation of the cold sores.
- Redness around the cold sore
- Fluid-filled sores
- Mild to moderate levels of pain in the sore
- Swollen glands in the neck region or some other body parts
- At times you will observe that 2-3 sores join together to form one big cold sore which becomes very painful.
One peculiarity of cold sore blisters is that they break open to release fluid and this fluid then dries and scabs off within 1-2 days.
How Are Cold Sores Different From Other Types of Sores, Say Canker Sores?
Other types of sores for e.g. canker sores which may look similar to cold sores are not contagious. This is one major differentiating point between cold sores and another type of sores. In addition to this, other sores are not caused by a virus. The main reason for the development of other sores (for e.g. canker sores are stress and injury of oral tissue etc.) whereas cold sores are caused by HSV as discussed before. So even if the appearance of different types of sores can be similar, they are not the same.
Your doctor can diagnose cold sores and differentiate them from other types of sores with the aid of some basic physical testing and some questions. In practice, no diagnostic test is utilized as such. However, if required, in order to confirm the existence of a cold sore your doctor can send blister sample for testing in a laboratory as a confirmatory test.
If the immune system which is nothing but your body’s defense system is weakened, the risk or chances of getting cold sores increases. Generally, people suffering from HIV/AIDS, patients undergoing cancer chemotherapy, patients who recently underwent organ transplantation etc. are at higher risk of getting infected by HSV and getting cold sores.
Usually the virus causing cold sores does not cause much harm; however, if the number starts increasing or due to some other reasons the virus starts to spread in other body parts as well. It can also result in certain complications like the spread of infection to the limbs, eye infections in case of spread to the eye resulting in vision problem or blindness, skin infections like eczema and even it can affect the spinal cord and brain resulting in serious health disorders.
How Can I Get Rid of Cold Sores?
In a large number of cases, the cold sores heal on their own in about 2-4 weeks. However for a better and quick healing following are the treatment options. We will also discuss some natural home remedies for a quick speedy recovery from cold sores.
