What does pruritus mean?

It is a medical term referring to an unpleasant skin sensation that creates an urge to scratch. Pruritus means itching. It can include itching with distinct skin lesions as well as itching with few visible changes.

How is it different from similar conditions?

Itching itself is not a disease name; causes vary and can include skin diseases, medications, or systemic conditions.

Why is this important in skin care?

Recording the affected area, time, presence of a rash, and any sleep disturbance will help in identifying the cause.

What should be checked based on my symptoms?

If generalized itching is accompanied by jaundice, fever, or weight changes, causes other than skin issues are also evaluated.

Condition GuidanceChronic PruritusChronic pruritus is a condition where itching lasts for 6 weeks or longer; instead of the initial rash, you may only see lines, scabs, or color changes caused by scratching. Since causes can include skin issues like dryness, eczema, or scabies, as well as new medications, neurological problems, or diseases of the liver, kidneys, thyroid, diabetes, and blood, we first organize the systemic distribution, medical history, and necessary tests. For itching that persists even after the cause is masked, we perform a pattern identification (Byeonjeung) focusing on body heat, dryness, sleep, digestion, and fatigue.Condition GuidanceLocalized PruritusLocalized pruritus is a condition where a specific area, such as one side of the back, an arm, or the scalp, is repeatedly itchy rather than the whole body. We first look for contact dermatitis, tinea, post-herpetic changes, and the itch-lichenification cycle; if pain, numbness, or burning occurs in the same area without a distinct rash, neuropathic itch is also checked. It is easier to narrow down the cause if you record the initial symptoms before the skin thickens from continuous scratching.Condition GuidanceSenile/Xerotic PruritusSenile and dry pruritus (itching) occurs as the skin thins with age and the ability to retain moisture and sebum decreases, leaving the calves, arms, and back rough and itchy. While hot baths, harsh soaps, and dry heating can worsen the condition, it is also necessary to check for new medications and conditions related to the liver, kidneys, thyroid, diabetes, or blood disorders. Rather than simply repeating moisturizing, we examine the distribution of the itching, quality of night sleep, skin lesions, and systemic changes.Medical Evaluation GuideThings to check when itching prevents sleep at nightFirst, check if the swollen areas generally fade within a day, or if rough and cracked skin remains for several days. If the wheals have subsided but you continue to wake up, record both the changes in the wheals and the number of times you woke up. If rough skin and scratch marks remain, the cycle of dermatitis and the itch-scratch cycle must be examined together. Even if there are few skin changes, please seek medical evaluation if generalized itching is accompanied by jaundice, weight changes, or fever.
