why do scars itch when they heal

It's normal for them to itch for years. Here's a "medical" explanation:

Wound healing is a very long and complex process which progresses in stages. Three stages of wound healing can be classified as: I. Inflamation; II. Proliferation; and III. Remodeling. These stages are fairly well understood and can be further broken down into specific cellular mechanisms that promote wound healing during each stage. The process can ultimately last for months or even years, depending on exactly where it is on the body, what type of tissue it is, and the kind of use that the tissue receives in terms of daily stretching and exposure to the environment. But in general, since sensation in and around the affected area comes from nerve endings (there are no nerve endings inside scar tissue. but there are all around scars), itching comes from stimulation of those endings. In early healing, such stimulation can come from the processes of healing itself. But later, the mechanical stretching of scar tissue next to normal tissues can stimulate nerve endings and cause an itching sensation. This is assuming there is no inflammation around the healed tissue. ~~~Just found these. you should try them out :)

When you were young did you ever fall off your bike and end up with a big gash in your leg or around your knee?


Do you remember what your mother told you besides to keep the area clean? She probably said, БStop scratching it. It canБt heal if you keep scratching. Б Mom knew that scratching could definitely re-open the wound and even introduce bacteria into it that would cause an infection. Why is it that scars itch? Surprisingly, scientists only have theories on the answer. But first of all, you should know that scars that itch are a big problem in those who have been burned and in keloid scars. In fact, sometimes scientists divide people with scars into two groups for Б those who have an itch on their scar six months or less after an injury that caused it (acute itch), and those who have itching more than six months after the injury (chronic itch).


Since scars can take a few years to heal, itБs conceivable that someone could have itching for the entire time! In one Texas study of 23 survivors, 87 percent had itching episodes daily. Ninety-six percent had three or more episodes daily. And hereБs the worst part Б 52 percent had itching attacks that lasted up to 30 minutes each episode. Ninety-four percent reported that itching was unbearable in the chronic itch group; 86% in the acute itch group. They complained of severe burning and crawling sensations. The good news is that as healing of the scar continued, the number of itch attacks decreased, as did the length of time the attack lasted. In China, doctors at the Southern Medical University found a significant difference between the beta-endorphin levels found around the nerve fibers in the skin of the scar. The patients who had itch without pain or itch with pain had significantly more beta-endorphin than those without pain or itch or in the control group. The researchers are thinking that thereБs some connection between beta-endorphin and itching, although they donБt know what exactly it is yet.


Beta-endorphin is the compound that your brain makes when youБre out running or exercising, listening to music, laughing or praying. When scars were analyzed, thereБs more than just beta-endorphin that can be found in the tissue. Scientists in Mexico City at a burn unit found Type 1 receptors for TNF-alpha in the blood vessels and IL-1beta in the keratinocytes and CD1a(+) cells. But like in the previous study, the scientists are still shaking their heads asking what it all means. Itching is possibly caused by inflammation in the skin around the. We know this is probably true because antihistamines reduce it. But did you know that thereБs a type of itch that antihistamines canБt reduce? This tells us that thereБs another part of the nervous system that is causing the nasty itch. It could result because of the activation of the opioid receptors found in the skin, reports Chinese scientists. Or maybe because itching is such a bother, the beta-endorphins are released in the skin to calm us all down! How much itching do you experience with your scar? Have you purchasedб б risk-free yet?
