Itching in the same area of ​​skin warns of what disease?

If the itching sensation recurs in the same location, appears almost every day and continuously for 6 weeks or more, it is considered chronic itching. This itching condition is not only uncomfortable but also significantly affects daily life, leading to difficulty sleeping and causing many other problems, according to the health website Verywell Health (USA).

Itching that lasts for more than 6 weeks is considered chronic itching and should be checked by a doctor.

Chronic itching can be particularly frustrating, especially when there is no relief. It can affect any part of the body and is accompanied by uncomfortable symptoms such as cracking, burning, and discoloration.

There are many causes of chronic itching. For example, if the itching starts in the upper arm and spreads to the neck and shoulders, it is often due to nerve damage. This condition is called brachioradial itching.

Another common type of chronic itching is anal itching. It is often caused by sweat, but it can also be caused by hemorrhoids. There is also another type of itching that usually occurs at night called Nocturnal pruritus.

Chronic itching can also be caused by allergies or psoriasis. However, not all cases of itchy skin are caused by a skin disease. Certain diseases, such as cirrhosis of the liver or high blood urea nitrogen due to kidney disease, can also cause generalized itching. Nerve compression and some psychological disorders can also lead to persistent itching.

Treatment will vary depending on the cause of the itch. If the itch is due to dryness or allergies, lotions or ointments will help relieve the itch. If lotions are not effective, over-the-counter creams such as cortisone and peppermint oil can be used.

If these methods continue to be ineffective, a doctor should be consulted. People with itching caused by neurological or psychological problems may be taught relaxation techniques and behaviors to reduce scratching, according to Verywell Health .
