It's normal for the muscles to relax, of course, but the brain gets confused. For a minute, it thinks you're falling. In response, the brain causes your muscles to tense as a way to "catch yourself" before falling down — and that makes your body jerk.
"The term for this is sleep myoclonus, or hypnic myoclonus, and occurs when your brain is shifting from one sleep phase to another.
Tremor is a neurological disorder that causes shaking movements in one or more parts of your body, most often in your hands. It can also occur in your arms, legs, head, vocal cords, and torso. Its rhythmic pattern is caused by unintentional (involuntary) muscle contractions.
Sometimes, however, people with MS experience symptoms that aren't associated with MS as often. One such symptom is internal tremors, which produce a quivering or vibrating sensation inside the body but don't cause external movement.
The most common experience of the buzzing feeling entails feeling like your muscles, fingers, or legs are vibrating or shaking inside. It's not the same thing as “nervous shaking.” Rather, it's like your body is acting like an electric toothbrush that goes on and vibrates in strange and unusual ways.
The stress hormones adrenaline and cortisol flood your system. Your muscles tense as all of this happens, then they release as the stressor fades, giving you the shakes. Anxiety shaking usually lasts until the stress response ends, which can be a few seconds or a few minutes.
Fatigue. Pain, which may be acute or chronic, caused by the nerves that carry sensation "short circuiting." Types of pain can include band-like pain around the chest, or MS hug, caused by spastic nerves along with other types of painful sensations in the neck, arms, legs and feet. Sexual problems.
Early MS symptoms may include blurred vision, numbness, dizziness, muscle weakness, and coordination issues. MS is progressive and can worsen over time. Eventually, the disease can do damage directly to the nerves, causing permanent disability.
Those symptoms include loss of vision in an eye, loss of power in an arm or leg or a rising sense of numbness in the legs. Other common symptoms associated with MS include spasms, fatigue, depression, incontinence issues, sexual dysfunction, and walking difficulties.
MS can appear at any age but most commonly manifests between the ages of 20 and 40. It affects women two to three times as often as men. Almost one million people in the United States have MS, making it one of the most common causes of neurological disability among young adults in North America.
Neurological examination
Your neurologist will look for abnormalities, changes or weakness in your vision, eye movements, hand or leg strength, balance and co-ordination, speech and reflexes. These may show whether your nerves are damaged in a way that might suggest MS.
Numbness or Tingling
Numbness of the face, body, or extremities (arms and legs) is often the first symptom experienced by those eventually diagnosed as having MS.
Blood Tests: Currently, there are no definitive blood tests for diagnosing MS, but they can be used to rule out other conditions that may mimic MS symptoms, including Lyme disease, collagen-vascular diseases, rare hereditary disorders and acquired immune deficiency syndrome (AIDS).
Average life span of 25 to 35 years after the diagnosis of MS is made are often stated. Some of the most common causes of death in MS patients are secondary complications resulting from immobility, chronic urinary tract infections, compromised swallowing and breathing.
Some people with MS find that their symptoms include changes to or problems with their toenails. MS can affect the toenails in a number of ways. Some are directly related to demyelination (damage to the myelin sheathing around nerves), while others are the indirect result of other MS symptoms.
Sensory nerve damage.
Early signs that you are experiencing sensory nerve damage from vibration include numbness or tingling in one or more of your fingers. This sensation might come and go, and could be mild, but severe cases can lead to permanent numbness.
What are the health effects of whole-body vibration? Whole-body vibration can cause fatigue, stomach problems, headache, loss of balance and "shakiness" shortly after or during exposure. The symptoms are similar to those that many people experience after a long car or boat trip.
