From definition, causes to treatment, find here everything about cold sores for having a better outlook on this disease.
What are Cold Sores?
Cold sores are red inflamed and fluid filled lesions that occur near the mouth and surrounding areas. However, in some cases they can occur on the nose, fingers or inside the mouth. Cold sores, also known as fever blisters, often occur in clusters and last for two weeks or longer. They are infectious and pass on through close contact like kissing.
What are the Causes of Cold Sores?
Herpes simplex virus or HSV 1 is responsible for the onset of cold sores. In some cases, it can be caused by HSV 2 occurring from performing fellatio with a person infected from genital herpes.
Can Cold Sores Come Back Once They are Healed?
Once you are infected with herpes simplex virus, it can’t be cured completely as it can strike you back even after healing. Therefore, you can have it again with the revival of the responsible virus.
Are Cold Sores Different from Canker Sores?
There is a difference between canker sores and cold sores. Sadly, cold sores are taken as canker sores due to the resemblance between these two blisters. Remember, canker sore is an ulcer developing under your mouth and is painful. Canker sores grow on the mouth’s soft tissues, but cold sores don’t.
What are the Symptoms of Cold Sores?
- Burning or tingling sensation on your lips or face days before the arrival of cold sores
- You will experience fever, muscle aches and swollen lymph nodes
- Fluid filled lesions pop up in clusters
(Note: See your physician immediately if you have eye problems during cold sores. HSV infection may harm your vision if it is not treated on time)
What are the Associated Risks of Cold Sores?
An outbreak of cold sores can invite certain health problems including infection, cold, fever, sun exposure, eczema, and even HIV and AIDS. Therefore, you must seek medical assistance in the initial stages of cold sores when blisters are about to pop up.
Though there is no cure for cold sores, there are certain medications to heal them. A doctor will prescribe you several antiviral ointments to be applied on your sores. You can also try OTC ointment to reduce the outbreak of canker sores. Apart from that, there are several oral antiviral medications which should be taken with doctor’s prescription only.
