One form of cancer that is accompanied by itching is polycythemia vera, one of several blood cancers called myeloproliferative disorders.

People with this kind of disease can experience itchiness especially after a warm bath or even hot shower, but this is only one of several symptoms that is associated with polycythemia vera. Others include trouble when breathing while lying down, headache and others.

Scaly skin may be an indication of Sezary Syndrome, which are cutaneous T-cell lymphoma. Mycosis fungoides goes through some phases, starting with red rashes which last for several months, followed by development of bumps or hardened lesions on skin, and tumors which form on skin and can be infected.

Pancreatic cancer is a disease where patients experience itching, but itching is not an indication of pancreatic cancer. In this type of cancer, patients experience itching if the tumor blocks the bile duct and leads to jaundice. When this happens, chemicals in bile leak into skin and lead to itching.

Some of the cancer treatments might lead to itchy skin no rash over entire body or even in isolated areas. This can due to a hypersensitivity reaction that occurs during chemotherapy infusion. In some of the cases, itching can be a chronic side effect of treatments, which includes biologic agents a variety of targeted drugs.

Itchy Skin No Rash Worse at Night

Itchy skin at night, known as nocturnal pruritus, may be severe enough to disrupt your sleep regularly. Why this occurs range from natural causes to serious health concerns.

Natural causes

For many people, natural mechanisms is suspected to be behind nighttime itch. Your body’s natural circadian rhythms influence skin functions such as temperature regulation, and barrier protection. These functions can then change at night. For instance, your body temperature and blood flow to skin both increase in evening, thus warming your skin. A rise in skin temperature might also make you feel itchy.

Your body’s release of some substances varies by time of day. At night, you release extra amount of cytokines, thus increasing inflammation. Meanwhile, production of the corticosteroids — which are hormones which reduce inflammation — slows.

On top of the factors, your skin then loses a lot of water at night. During the dry winter months, your parched skin itches.

When itchiness occurs during the day, work and several other activities distract you from annoying sensation. At night there are very few distractions, which makes the itch feel more intense.

Health-related causes

Along with your body’s natural circadian rhythms, several health conditions can lead to the itchy skin to becoming worse at night. These are:

  • skin diseases like atopic dermatitis, psoriasis, and hives
  • bugs like scabies, bed bugs and pinworms
  • iron deficiency anemia
  • psychological conditions like stress and schizophrenia
  • cancers like leukemia and lymphoma
  • nerve disorders, like multiple sclerosis and diabetes
  • allergic reactions to substances such as chemicals, drugs or cosmetics

Itchy Skin No Rash Stress

Because there are several medical conditions which leads to cause anxiety and anxiety-like sensations and symptoms, which includes this one, it is recommended that all new, persistent, and also returning symptoms be reported to your doctor.

If your doctor observes that your sensations and symptoms are solely stress related, you might then be confident that there isn’t another medical reason behind their occurrence.

Generally, most of the doctors can tell the difference between stress- and anxiety-caused sensations and symptoms from those brought about by several other medical conditions.

If you are not sure about your doctor’s diagnosis, however, you may want to seek a second opinion. But if all the opinions concur, you might then be assured that stress is the cause of your sensations and symptoms and no other medical or biological problem.

If your itching and burning skin sensation is attributed to anxiety and stress, then behaving apprehensively makes the body to activate the stress response, bringing about specific physiological, and emotional changes in body so as to enhance the body’s ability to deal with a threat. Because of the nature of the changes, the stress response is usually known as the fight or flight response.

Because stress responses lead to such dramatic changes in the body, they stress the nervous system which is responsible for sending and receiving sensory information to and from brain, including sensory information from the nerve endings in skin.

A body which becomes stress-response hyperstimulated can behave in erratic ways. Experiencing itching and also burning of skin for no good reason is an example the body’s nervous system and sensory organs can ‘misbehave’ because of being overly stressed.

While anxiety and stress caused itchy skin no rash and burning skin sensations are unusual, they aren’t an indication of a serious medical problem. It’s one more way that a stress-response hyperstimulated body produces odd and erratic symptoms.

Itchy Skin No Rash Liver

Itchy skin, can happens with a several medical conditions and can be distressing. Liver diseases with bile obstruction have itching as a symptom, but the reason for the itching is not clearly indicated. Treatment requires either reversing of the bile obstruction or even medications that can used to suppress the itch.

Cholestatic Liver Disease

Your liver continuously produces bile, thus assisting in removal of the wastes and your intestines absorb dietary fat. Bile is usually produced in liver cells, travels out of bile ducts via the pancreas and finally empties into small intestine. A blockage which is anywhere along the pathway may stop the flow of bile — cholestasis — and can cause increased levels of bile in the bloodstream.

Yellowing of skin and eyes, dark urine as well as light stools usually appear as the bile levels climb, normally accompanied by the widespread itching. Bile flow obstruction can happen inside the liver — for instance, because of hepatitis, drug use or even pregnancy; or it can happen outside the liver, because of gallstones or inflammation of the pancreas.

Pruritus and Liver Disease

Widespread itching from liver disease appears before other symptoms of cholestasis develop. Itching is most severe on palms and soles of the feet, and worse in late evening and also at night. No rash or other lesions are present, except when scratching itself damages skin.

Unless liver disease is the cause of itching, your doctor will perform tests so as to confirm the diagnosis, which includes a blood bilirubin level, liver function tests and a liver ultrasound so as to look for bile duct changes.

Explanation for Cholestatic Itching

The reason for generalized itching with the liver disease is not well indicated, other than apparent link that exists with obstructed bile flow.

Bile salts, chemicals that are closely related to bile, are then deposited in skin while the bilirubin levels rise and have been said to be the primary cause of itching. Research on a protein known as autotaxin as the potential cause for Cholestatic itching, which can eventually cause new treatment options.

Detailed research as well as explanations are very difficult when a symptom like itching happens with several diseases, is experienced differently by each individual and responds to different treatments in the different cases.

 

Treatment of Itching With Cholestasis

Resolving the cause of bile flow obstruction has been established as the best treatment that is used for itching with liver disease, but when it isn’t possible several medications might assist to relieve the itch. Cholestyramine is used often, and works by binding bile salts in intestines so that they are excreted rather than being reabsorbed back into bloodstream.

Rifampicin, causes an increase in the liver metabolism of bile and several other chemicals, and relieves the itching in most of the people. Drugs which block opioid receptors in body also of help, indicating that your body’s own endorphins can play a crucial role in pruritus. Stopping drugs which may further harm the liver, like alcohol, is also recommended.
