cold sore are generally caused by the herpes simplex1 virus. It may also be caused by a group of related viruses called the Herpes Simplex Virus that includes cold sores known as fever blisters. Cold sore outbreaks tend to be triggered by being exposed to cold weather, exposure to warm sun, cold air, a recent cold or injury, an undeveloped sore, or pressure from stress. These outbreaks can last for days or weeks and have been known to occur up to three times each year.
When they do occur it is essential to get them treated right away. This is because cold sores are known to last anywhere from one day to two weeks and can be very painful. During these outbreaks the skin will become raw and sensitive causing pain and discomfort during eating or in sports activities. Some people even notice that their lips and teeth start to hurt while others notice redness in the affected areas. If you have any open wounds or cuts during an outbreak you should seek medical attention immediately so that they can be properly treated. During an active cold sore outbreak your healthcare provider will likely prescribe an antiviral medication to help clear up the virus.
While there are many factors that can trigger cold sore outbreaks, the main trigger seems to be coming into direct contact with someone who has the virus. This is why you should not touch anyone else's cold sore. If you do touch someone who has an outbreak it is important to wash your hands immediately and try to avoid any close contact until the sore has gone. If you do need to touch your cold sore you should wash your hands thoroughly and try to keep the area as clean as possible to reduce the chances of passing on the virus. You should also not share personal items like towel and toothbrush because the virus can be spread this way.
People often call them fever blisters but they are actually a type of cold sore. They have similar characteristics as a normal cold sore, however they are filled with fluid-filled blisters. A fever blister is often called fever blisters because the intense burning sensation is similar to what is felt when a fever blister is open.
There are many different symptoms of cold sores that vary depending on how advanced the outbreak. These symptoms include extreme burning and or tingling, pain, itching, discharge, redness, swelling, and pain around the infected area. These symptoms can occur anywhere on the body but tend to appear most often on the lips, face, or eyelids. The outbreaks tend to come and go and may never disappear completely.
Some people can have mild cold sore outbreaks that only last a few days. These are generally easy to treat at home. Others can have severe outbreaks that cause severe pain, itching, bleeding, and swelling. When you have symptoms like these it is important that you visit a doctor so they can help treat them and get cold sores under control before they get out of hand and cause permanent damage.
