Warning signs are clues your body sends that your brain is not receiving enough oxygen. If you observe one or more of these signs of a stroke or “brain attack,” don’t wait, call a doctor or 911 right away! -Sudden numbness or weakness of face, arm, or leg, especially on one side of the body -Sudden confusion, or trouble talking or understanding speech -Sudden trouble seeing in one or both eyes -Sudden trouble walking, dizziness, or loss of balance or coordination -Sudden severe headache with no known cause Other danger signs that may occur include double vision, drowsiness, and nausea or vomiting. Sometimes the warning signs may last only a few moments and then disappear. These brief episodes, known as transient ischemic attacks or TIAs, are sometimes called “mini-strokes.” Although brief, they identify an underlying serious condition that isn’t going away without medical help. Unfortunately, since they clear up, many people ignore them. Don’t. Paying attention to them can save your life.
Raynaud’s disease is a condition that causes some areas of your body — such as your fingers, toes, the tip of your nose and your ears — to feel numb and cool in response to cold temperatures or stress. In Raynaud’s disease, smaller arteries that supply blood to your skin narrow, limiting blood circulation to affected areas. Women are more likely to have Raynaud’s disease. It’s also more common in people who live in colder climates.
Treatment of Raynaud’s disease depends on its severity and whether you have any other health conditions. For most people, Raynaud’s disease is more a nuisance than a disability. Raynaud’s disease is more than simply having cold hands and cold feet, and it’s not the same as frostbite. Signs and symptoms of Raynaud’s depend on the frequency, duration and severity of the blood vessel spasms that underlie the disorder. Raynaud’s disease symptoms include: -Cold fingers and toes
-Sequence of color changes in your skin in response to cold or stress -Numb, prickly feeling or stinging pain upon warming or relief of stress During an attack of Raynaud’s, affected areas of your skin usually turn white at first. Then, the affected areas often turn blue, feel cold and numb, and your sense of touch is dulled. As circulation improves, the affected areas may turn red, throb, tingle or swell. The order of the changes of color isn’t the same for all people, and not everyone experiences all three colors. Occasionally, an attack affects just one or two fingers or toes. Attacks don’t necessarily always affect the same digits. Although Raynaud’s most commonly affects your fingers and toes, the condition can also affect other areas of your body, such as your nose, lips, ears and even nipples. An attack may last less than a minute to several hours. People who have Raynaud’s accompanied by another disease will likely also have signs and symptoms related to their basic underlying condition.
Multiple sclerosis (MS) is a potentially debilitating disease in which your body’s immune system eats away at the protective sheath (myelin) that covers your nerves. Damage to myelin causes interference in the communication between your brain, spinal cord and other areas of your body. This condition may result in deterioration of the nerves themselves, a process that’s not reversible. Multiple sclerosis has no cure. However, treatments may help treat MS attacks, manage symptoms and reduce progress of the disease.
Symptoms of multiple sclerosis vary, depending on the location of affected nerve fibers. Multiple sclerosis symptoms may include: -Numbness or weakness in one or more limbs -Partial or complete loss of central vision, usually in one eye, often with pain during eye movement (optic neuritis)
-Double vision or blurring of vision -Tingling or pain in parts of your body -Electric-shock sensations that occur with certain head movements -Tremor, lack of coordination or unsteady gait -Slurred speech -Fatigue -Dizziness
Heat sensitivity is common in people with multiple sclerosis. Small increases in body temperature can trigger or worsen multiple sclerosis symptoms. Some people have a benign form of multiple sclerosis. In this form of the disease, the condition remains stable and often doesn’t progress to serious forms of MS after the initial attack.

Alcoholic neuropathy is damage to the nerves that results from excessive drinking of alcohol. Causes- The cause of alcoholic neuropathy is debated. It probably includes both a direct poisoning of the nerve by the alcohol, and the effect of poor nutrition associated with alcoholism. Up to half of all long-term heavy alcohol users develop this condition.
In severe cases, the nerves that regulate internal body functions (autonomic nerves) may be involved.
Risks for alcoholic neuropathy include:
Long-term, heavy alcohol use
Alcoholism that is present for 10 years or more Symptoms: Numbness in the arms and legs Abnormal sensations; “pins and needles” Painful sensations in the arms and legs Muscle weakness Muscle cramps or muscle aches Heat intolerance, especially after exercise Impotence (in men) Problems urinating Constipation
A pinched nerve occurs when too much pressure is applied to a nerve by surrounding tissues, such as bones, cartilage, muscles or tendons. This pressure disrupts the nerve’s function, causing pain, tingling, numbness or weakness.
A pinched nerve can occur at several sites in your body. A herniated disk in your lower spine, for example, may put pressure on a nerve root, causing pain that radiates down the back of your leg. Likewise, a pinched nerve in your wrist can lead to pain and numbness in your hand and fingers (carpal tunnel syndrome).
With rest and other conservative treatments, most people recover from a pinched nerve within a few days or weeks. Sometimes, surgery is needed to relieve pain from a pinched nerve. Your doctor will ask about your symptoms and conduct a physical examination.
If your doctor suspects a pinched nerve, you may undergo some tests. These tests may include: Nerve conduction study. This test measures electrical nerve impulses and functioning in your muscles and nerves. A specialist places electrodes on your skin. The study measures the electrical impulses in your nerve signals when a small current passes through the nerve.
Test results tell your doctor whether you have a damaged nerve. Electromyography. During an EMG, your doctor inserts a needle electrode through your skin into various muscles. The test evaluates the electrical activity of your muscles when they contract and when they’re at rest.
Test results tell your doctor if there is damage to the nerves leading to the muscle. Magnetic resonance imaging (MRI). This test uses a powerful magnetic field and radio waves to produce detailed views of your body in multiple planes.
This test may be used if your doctor suspects you have nerve root compression.
