numbness and burning sensation throughout my body?

Question

Awhile ago I went to the doctor for a numbness burning sensation in my legs. She ran some blood tests which ruled out limes disease, diabites, and a whole bunch of other stuff. Then she sent me to a Nurologest. He ran this test on me where he shocked my legs and feet. We then got the test results back and found that i dont have a pinched nurve or a sliped disk. so on we went to a C-spine MRI checking for Multipal Sclorsis. That also came back negative. now i have to go for another MRI this time on my brain. since all these tests the numbness is now all over my body my arms and legs, and face and neck nose, ears fingers and toes. the burning sensation is killing me it hurts so bad.
So my question to everyone is: Has this happened to you or somebody you know? Can anyone give me any idea as to whats going on with me.? Is there anything I can do to fix this problem. please help me out.

thanks for your help

Answer 1

Numbness and tingling


Definition

Numbness and tingling are decreased or abnormal sensations caused by altered sensory nerve function.

Description

The feeling of having a foot "fall asleep" is a familiar one. This same combination of numbness and tingling can occur in any region of the body and may be caused by a wide variety of disorders. Sensations such as these, which occur without any associated stimulus, are called paresthesias. Other types of paresthesias include feelings of cold, warmth, burning, itching, and skin crawling.

Causes and symptoms

Causes

Sensation is carried to the brain by neurons (nerve cells) running from the outer parts of the body to the spinal cord in bundles called nerves. In the spinal cord, these neurons make connections with other neurons that run up to the brain. Paresthesias are caused by disturbances in the function of neurons in the sensory pathway. This disturbance can occur in the central nervous system (the brain and spinal cord), the nerve roots that are attached to the spinal cord, or the peripheral nervous system (nerves outside the brain and spinal cord).

Peripheral disturbances are the most common cause of paresthesias. "Falling asleep" occurs when the blood supply to a nerve is cut off--a condition called ischemia. Ischemia usually occurs when an artery is compressed as it passes through a tightly flexed joint. Sleeping with the arms above the head or sitting with the legs tightly crossed frequently cause numbness and tingling.

Direct compression of the nerve also causes paresthesias. Compression can be short-lived, as when a heavy backpack compresses the nerves passing across the shoulders. Compression may also be chronic. Chronic nerve compression occurs in entrapment syndromes. The most common example is carpal tunnel syndrome. Carpal tunnel syndrome occurs when the median nerve is compressed as it passes through a narrow channel in the wrist. Repetitive motion or prolonged vibration can cause the lining of the channel to swell and press on the nerve. Chronic nerve root compression, or radiculopathy, can occur in disk disease or spinal arthritis.

Other causes of paresthesias related to disorders of the peripheral nerves include:

* Metabolic or nutritional disturbances. These disturbances include diabetes, hypothyroidism (a condition caused by too little activity of the thyroid gland), alcoholism, malnutrition, and vitamin B12 deficiency.

* Trauma. Trauma includes injuries that crush, sever, or pull on nerves.

* Inflammation.

* Connective tissue disease. These diseases include arthritis, systemic lupus erythematosus (a chronic inflammatory disease that affects many systems of the body, including the nervous system), polyarteritis nodosa (a vascular disease that causes widespread inflammation and ischemia of small and medium-size arteries), and Sjögren's syndrome (a disorder marked by insufficient moisture in the tear ducts, salivary glands, and other glands).

* Toxins. Toxins include heavy metals (metallic elements such as arsenic, lead, and mercury which can, in large amounts, cause poisoning), certain antibiotics and chemotherapy agents, solvents, and overdose of pyridoxine (vitamin B6).

* Malignancy.

* Infections. Infections include Lyme disease, human immunodeficiency virus (HIV), and leprosy.

* Hereditary disease. These diseases include Charcot-Marie-Tooth disease (a hereditary disorder that causes wasting of the leg muscles, resulting in malformation of the foot), porphyria (a group of inherited disorders in which there is abnormally increased production of substances called porphyrins), and Denny-Brown's syndrome (a hereditary disorder of the nerve root).

Paresthesias can also be caused by central nervous system disturbances, including stroke, TIA (transient ischemic attack), tumor, trauma, multiple sclerosis, or infection.

Symptoms

Sensory nerves supply or innervate particular regions of the body. Determining the distribution of symptoms is an important way to identify the nerves involved. For instance, the median nerve innervates the thumb, the first two fingers, half of the ring finger, and the part of the hand to which they connect. The ulnar nerve innervates the other half of the ring finger, the little finger, and the remainder of the hand. Distribution of symptoms may also aid diagnosis of the underlying disease. Diabetes usually causes a symmetrical "glove and stocking" distribution in the hands and feet. Multiple sclerosis may cause symptoms in several, widely separated areas.

Other symptoms may accompany paresthesias, depending on the type and severity of the nerve disturbance. For instance, weakness may accompany damage to nerves that carry both sensory and motor neurons. (Motor neurons are those that carry messages outward from the brain.)

Diagnosis

A careful history of the patient is needed for a diagnosis of paresthesias. The medical history should focus on the onset, duration, and location of symptoms. The history may also reveal current related medical problems and recent or past exposure to drugs, toxins, infection, or trauma. The family medical history may suggest a familial disorder. A work history may reveal repetitive motion, chronic vibration, or industrial chemical exposure.

The physical and neurological examination tests for distribution of symptoms and alterations in reflexes, sensation, or strength. The distribution of symptoms may be mapped by successive stimulation over the affected area of the body.

Lab tests for paresthesia may include blood tests and urinalysis to detect metabolic or nutritional abnormalities. Other tests are used to look for specific suspected causes. Nerve conduction velocity tests, electromyography, and imaging studies of the affected area may be employed. Nerve biopsy may be indicated in selected cases.

Treatment

Treatment of paresthesias depends on the underlying cause. For limbs that have "fallen asleep," restoring circulation by stretching, exercising, or massaging the affected limb can quickly dissipate the numbness and tingling. If the paresthesia is caused by a chronic disease such as diabetes or occurs as a complication of treatments such as chemotherapy, most treatments are aimed at relieving symptoms. Anti-inflammatory drugs such as aspirin or ibuprofen are recommended if symptoms are mild. In more difficult cases, antidepressant drugs such as amitriptyline (Elavil) are sometimes prescribed. These drugs are given at a much lower dosage for this purpose than for relief of depression. They are thought to help because they alter the body's perception of pain. In severe cases, opium derivatives such as codeine can be prescribed.Currently trials are being done to determine whether treatment with human nerve growth factor will be effective in regenerating the damaged nerves.

Alternative treatment

Several alternative treatments are available to help relieve symptoms of paresthesia. Nutritional therapy includes supplementation with B complex vitamins, especially vitamin B 12 (intramuscular injection of vitamin B12 is most effective). Vitamin supplements should be used cautiously however. Overdose of Vitamin B6 is one of the causes of paresthesias. People experiencing paresthesia should also avoid alcohol. Acupuncture and massage are said to relieve symptoms. Self-massage with aromatic oils is sometimes helpful. The application of topical ointments containing capsaicin, the substance that makes hot peppers hot, provides relief for some. It may also be helpful to wear loosely fitting shoes and clothing. None of these alternatives should be used in place of traditional therapy for the underlying condition.

Prognosis

Treating the underlying disorder may reduce the occurrence of paresthesias. Paresthesias resulting from damaged nerves may persist throughout or even beyond the recovery period. The overall prognosis depends on the cause.

Prevention

Preventing the underlying disorder may reduce the incidence of paresthesias. For those with frequent paresthesias caused by ischemia, changes in posture may help.

Answer 2

Burning Sensation Throughout Body

Answer 3

Numbness All Over Body

Answer 4

Were you bitten by an insect recently? I have a friend who went through the exact same scenario as you... but she knew she'd been bitten by mosquitos just before the symptoms hit. In the end, after 8 weeks of the same symptoms as you are having, the symptoms went away... It was a VIRUS all the time!! So, with all of the tests coming back negative, and knowing these symptoms could be a virus, please don't panic. Each negative test is not taking you closer to doom, but closer to the possibility that everything will just clear up on its own!! :-)

Could be fibromyalgia??
My mom had and still has Similar symptoms and went through all the testing and MRI’s.
She had this done two years ago and the doc says its fibromyalgia.

Now, last month. Her doctor tells her she has herniated discs.

Best of luck and I hope you feel better soon!

Answer 10

Have you been exposed to any heavy metals (such as mercury) or any poisonous agents such as arsenic?
