An itch is a very slight form of pain from your nerves. There is usually something touching you and your body feels threatened by the contact, and so you itch to remove it from your skin.

In bites and stings it's because the nerves are stimulated by the poison/acid/alkali released into the bite.

Sometimes you may feel a 'Phantom' or travelling itch, when you can't quite tell where you need to itch. This is caused by random stimulation of the nerve, the cause of which is unknown

Itching usually occurs when our skin is irritated or has been in contact with something that triggers a histamine response from our immune system. This response can be due to various factors such as insect bites, Allergies, dry skin, or skin conditions like eczema. Scratching the itch provides temporary relief but can also cause further irritation.
