On a physical level, itching is actually linked to neurotransmitters, notably histamine, which is a chemical molecule that is released by certain cells into the blood. When neurotransmitters are released by these cells, they attach themselves to nerve receptors in the skin to transmit the itching sensation to the brain. This is why you feel the need to scratch an itch.
What causes itching?
Itches can be divided into two categories: localized (on a specific area of the skin) and generalized (which can affect the entire skin’s surface). Once the itch has been categorized, the diagnostic as to its causes can be made.
Here are the main causes of localized itches:
- Infections: mycosis, bacterial infections, viral infections, etc.
- Infestations: mites, arthropod bites, lice, etc.
- Prurigos: insect bites, animal fur, plants, etc.
Here are the main causes of generalized itching:
- Flare-ups and inflammation: eczema, psoriasis, hives, hyper-sensitivity, medication, etc.
- Neoplasm: lymphoma (a cancer that affects the immune system), spinocellular carcinoma (a form of skin cancer that appears as small hard masses on the skin), etc.
- Hereditary or congenital diseases: Darier’s disease (a rare and hereditary disease of the skin), Hailey-Hailey disease (a genetic diseases that causes blisters on the skin), etc.
How can I treat itching?
There are several treatments that can help minimize flare-ups and reduce the discomfort of chronic itching. These include emollient creams, oleo-calcareous liniments, and cortisone-based anti-allergens. However, these treatments can cause side effects in some people, including hyper-sensitivity and burning sensations, caused particularly by limewater in oleo-calcareous liniments. When used long-term, cortisone-based anti-allergens lose their effectiveness and can cause negative side effects, such as the thinning of the skin.
