Question itchy scabs? - December 10th 2010, 06:25 PM

So I know you all aren't doctors but i was wondering why scabs and sometimes cuts itch? I was told the itching meant it was healing. Is that really true? What causes it?

I'm not sure what causes itching around cuts and scabs. Try googling it? I do know it's normal though. It happens to me sometimes too.

Itching 101

Scabs itch for several reasons. First of all, scabs contain histamines, which naturally irritates the skin surrounding the scab, causing it to itch. Doctors theorize that this may be the body's natural way to help the body rid itself of the scab when the scab has served its purpose and is no longer needed - it itches, you scratch it and the scab falls off. Unfortunately, scabs usually itch long before they are ready to fall off, leading to other theories as to why scabs itch.
When your skin is compromised, there are specific tiny nerves in the upper layers of skin that are sensitive to touch. These nerves can send itching sensations to the brain, causing the brain to think the skin is being tickled. When your skin is severed, these nerves are also severed. As these nerves heal along with the rest of your skin, the nerves may send signals to the brain that are misinterpreted by the brain as an itch, causing you to feel itchy even though there is no reason to scratch that healing spot.
A final theory behind this question is that the scab, while healing, begins to pull away from the new skin, and this pulling causes the scab to itch.

I found this on google. A site called life123 (:

Hope it answers your question.
