Why Scratching feels so good (But Is So Bad)

When you’ve got an itch, you probably want to scratch it. But whether it’s from a mosquito bite, chickenpox, or chronic skin issue like eczema, any relief from scratching will be short-lived. And too much scratching can make the problem much worse.

Your muscles, joints, and organs can hurt. But your skin is the only part of your body that can feel both pain and itch.

An itch can be triggered by something outside your body, such as poison ivy, or by something happening on the inside, such as psoriasis or allergies.

Though it feels good, scratching actually triggers mild pain in your skin. Nerve cells tell your brain something hurts, and that distracts it from the itch. It can make you feel better in that moment, but 1 in 5 people say scratching makes them itch somewhere else on their body.

Sometimes the pain from scratching makes your body release the pain-fighting chemical serotonin. It can make the itch feel even itchier.

That’s why the more you scratch, the more you itch. The more you itch, the more you scratch. This cycle can be tough to break, especially if your itch is really bad.

Not all itches are alike. Many happen when your body reacts to pollen, nuts, and other allergens – your immune system makes a chemical called histamine. Others come from a problem with your nervous system, like shingles or a stroke. With those, you might feel numbness and tingling along with the itch.

If you have psoriasis, your itching may feel more like burning. Some people compare it to being attacked by fire ants. Some drugs, like one used to treat malaria, cause a painful all-over itch.

Whatever the reason, it’s important not to scratch too much. It can lead to skin wounds, infections, and scarring. It can also make you feel anxious and stressed.
