In some rare cases, night sweats in men can appear as a symptom of cancer or certain neurological diseases, including stroke. Neurological Diseases A neurological disease is any problem that affects the nervous system – the brain and spinal cord and the nerves in the rest of the body. There are hundreds of neurological disorders, although some are more common than others. Some neurological problems can rarely present with night sweats. These include: Stroke; Syringomyelia; Autonomic dysreflexia; Autonomic neuropathy; Symptoms of neurological problems can vary widely. Along with night sweats, you may also experience: Numbness or weakness in the hands, feet and limbs; Decreased appetite; Pain and stiffness throughout the body; Dizziness or fainting; It is necessary to seek emergency medical help if suddenly: The victim cannot speak or cannot articulate words clearly; Has one-sided blurred vision or loss of vision; There is paralysis of a limb; There is drooping on one side of the face; There is severe pain in the head. These are signs of a stroke, which can be life-threatening. Chances of recovery increase with immediate medical attention. Cancer Although unusual, night sweats can be a sign of cancer. It should be noted that cancer usually includes other symptoms, such as persistent fever and weight loss. These symptoms can vary and may appear sooner or later, depending on the type and severity of the cancer. Leukemia and lymphoma (Hodgkin or Non-Hodgkin) are two main types of cancer that can present with night sweats as a symptom. Other symptoms may be noticed which include: Severe fatigue or weakness; Unexplained weight loss; Chills; Enlargement of lymph nodes; Bone pain; Chest or abdominal pain Sometimes early symptoms of cancer can be missed because they appear to be related to other problems. If you have frequent night sweats, feel very tired and run down, or have flu-like symptoms that do not improve, you should see a doctor to find out the cause of the condition.
