1.Very dry skin.
Extremely dry skin can be intensely itchy.
- Bug bites.
When a mosquito bites you, the cause of your itchy skin is usually obvious, and the itch tends to go away quickly. When bugs live on your skin or feed on you every night, the itch can be long-lasting and uncontrollable. Bugs that can cause long-lasting itch, include bed bugs, lice, and mites (scabies).
- Skin cancer.
For many people, the only sign of skin cancer is a new or changing spot on their skin. Sometimes, that spot also itches and can be the only reason a person notices the spot.
- Reaction to a plant or marine life.
Plants – Poison ivy is famous for causing an itchy rash, but it’s not the only plant that can do so. If you’re unaware that a plant is causing your itch, the itch can be long-standing. Here’s a guide to plants in the United States that can make you itch at, Plants that can make you itch.
Marine life – You can also get an itchy rash after being in water, such as an ocean, lake, or pond.
- Allergic skin reaction.
Our skin can develop an allergic reaction to many substances. One of the most common substances that can cause an allergic skin reaction is nickel, which is found in many products that we touch every day. Products that contain nickel include cell phones, jewellery, eyeglass frames, zippers, and belt buckles.
- Itchy skin condition.
The list of skin conditions that can cause intense itch is long and includes:
- Hand-foot-and-mouth disease
- Seborrheic dermatitis
- Medication or cancer treatment.

- Nerve problem.
When a nerve isn’t working properly, it can cause itchy skin. If there’s damage along a nerve due to disease or injury, you can also develop itchy skin. This itch tends to occur in one place on your body and you don’t see a rash.
It makes your body overproduce skin cells, which pile up in itchy, inflamed patches on the skin’s surface. This is a result of an overactive immune system.
- Eczema or atopic dermatitis
It shows up on your skin as dry, scaly patches or a bumpy rash. It isn’t clear what causes it, but it’s extremely itchy. Kids are more likely to get it if their family has a history of asthma and allergies. Certain food allergies can make it worse.
