You may have itchy skin over certain small areas, such as on an arm or leg, or your whole body may itch. Itchy skin can occur without any other noticeable changes on the skin. Or it may be associated with:
- Bumps, spots or blisters
- Dry, cracked skin
- Leathery or scaly texture to the skin
Sometimes itchiness lasts a long time and can be intense. As you rub or scratch the area, it gets itchier. And the more it itches, the more you scratch. Breaking this itch-scratch cycle can be difficult, but continued scratching can damage your skin or cause infection.
When to see a doctor
See your doctor or a skin disease specialist (dermatologist) if the itching:
