As a medical expert, it's important to note that itching all over the body without a visible rash can be a symptom of various underlying conditions. It's crucial to approach this symptom with a holistic perspective, considering both external and internal factors that might be at play.

Dry Skin is one of the most common causes of generalized pruritus, especially in individuals over the age of 65. The skin naturally loses moisture as we age, which can lead to dryness and itching. This can be exacerbated by cold weather, low humidity, and the use of harsh soaps or detergents.

Medications can also induce itching as a side effect. Certain drugs, including some antibiotics, antidepressants, and pain medications, are known to cause pruritus. If you've recently started a new medication and developed itching, it's worth discussing this with your healthcare provider.

Internal Diseases can manifest as itching without a rash. Conditions such as liver disease, kidney disease, and thyroid disorders can affect the body's metabolism and lead to itching. Additionally, some cancers, particularly lymphomas, can cause systemic itching.

Neurological Conditions like multiple sclerosis or diabetic neuropathy can cause itching due to nerve irritation or damage. The nervous system plays a critical role in how the body perceives sensations, including itchiness.

Psychological Factors such as stress and anxiety can also lead to itching. The mind and body are closely connected, and psychological states can have a profound effect on physical sensations.

Allergic Reactions to food, environmental factors, or insect bites can cause itching even in the absence of a rash. This is the body's immune response to perceived threats.

Infections, including fungal, bacterial, or parasitic infections, can lead to itching. For example, scabies is a parasitic infection that causes intense itching.

Hormonal Changes, particularly in women, can lead to itching. Conditions like polycystic ovary syndrome (PCOS) can cause hormonal imbalances that result in itching.

Poor Blood Circulation can also result in itching. When blood flow is restricted, it can lead to a lack of nutrients and oxygen reaching the skin, causing discomfort and itchiness.

It's essential to consult with a healthcare provider to identify the cause of itching. They may perform a physical examination, ask about your medical history, and possibly order blood tests or other diagnostic procedures to pinpoint the issue. Once the cause is identified, appropriate treatment can be initiated to alleviate the discomfort.
