Tingling hand!!!
(carpal tunnel syndrome)

Carpal tunnel syndrome is pressure on the median nerve -- the nerve in the wrist that supplies feeling and movement to parts of the hand. It can lead to numbness, tingling, weakness, or muscle damage in the hand and fingers.


 Symptoms

wasting of hand muscles as seen in
long term carpal tunnel syndrome
paresthesia and tingling of hand




distribution of pain and numbness


  • Numbness or tingling in the thumb and next two or three fingers of one or both hands
  • Numbness or tingling of the palm of the hand
  • Pain extending to the elbow
  • Pain in wrist or hand in one or both hands
  • Problems with fine finger movements (coordination) in one or both hands
  • Wasting away of the muscle under the thumb (in advanced or long-term cases)
  • Weak grip or difficulty carrying bags (a common complaint)
  • Weakness in one or both hands

Signs and tests

During a physical examination, the doctor  may find:
  • Numbness in the palm, thumb, index finger, middle finger, and thumb side of the ring finger
  • Weak hand grip
  • Tapping over the median nerve at the wrist may cause pain to shoot from the wrist to the hand (this is called Tinel's sign)
  • Bending the wrist forward all the way for 60 seconds will usually result in numbness, tingling, or weakness (this is called Phalen's test)
Tests may include:

  • Electromyography
  • Nerve conduction velocity
  • Wrist x-rays should be done to rule out other problems (such as wrist arthritis)


Causes, incidence, and risk factors

The median nerve provides feeling and movement to the "thumb side" of the hand (the palm, thumb, index finger, middle finger, and thumb side of the ring finger).
The area in your wrist where the nerve enters the hand is called the carpal tunnel. This tunnel is normally narrow, so any swelling can pinch the nerve and cause pain, numbness, tingling or weakness. This is called carpal tunnel syndrome.
Carpal tunnel syndrome is common in people who perform  repetitive motions of the hand and wrist. Typing on a computer keyboard is probably the most common cause of carpal tunnel. Other causes include:
  • Sewing
  • Driving
  • Assembly line work
  • Painting
  • Writing
  • Use of tools (especially hand tools or tools that vibrate)
  • Sports such as racquetball or handball
  • Playing some musical instruments
The condition occurs most often  in people 30 to 60 years old, and is more common in women than men.
A number of medical problems are associated with carpal tunnel syndrome, including:
 
  • Bone fractures and arthritis of the wrist
  • Acromegaly
  • Diabetes
  • Alcoholism
  • Hypothyroidism
  • Kidney failure and dialysis
  • Menopause, premenstrual syndrome (PMS), and pregnancy
  • Infections
  • Obesity
  • Rheumatoid arthritis, systemic lupus erythematosus (SLE), and scleroderma
 
Treatment

You may try wearing a splint at night for several weeks. If this does not help, you may need to try wearing the splint during the day. Avoid sleeping on your wrists. Hot and cold compresses may also be recommended.
There are many changes you can make in the workplace to reduce the stress on your wrist:
  • Special devices include keyboards, different types of mouses, cushioned mouse pads, and keyboard drawers.
  • Someone should review the position you are in when performing your work activities. For example, make sure the keyboard is low enough so that your wrists aren't bent upward while typing. Your doctor may suggest an occupational therapist.
  • You may also need to make changes in your work duties or recreational activities. Some of the jobs associated with carpal tunnel syndrome include those that involve typing and vibrating tools. Carpal tunnel syndrome has also been linked to professional musicians.

MEDICATIONS
Medications used in the treatment of carpal tunnel syndrome include nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen. Corticosteroid injections, given into the carpal tunnel area, may relieve symptoms for a period of time.

                                                               Corticosteroid injections

SURGERY
Carpal tunnel release is a surgical procedure that cuts into the ligament that is pressing on the nerve. Surgery is successful most of the time, but it depends on how long the nerve compression has been occurring and its severity.

Expectations
Symptoms often improve with treatment, but more than 50% of cases eventually require surgery. Surgery is often successful, but full healing can take months.

Complications
If the condition is treated properly, there are usually no complications. If untreated, the nerve can be damaged, causing permanent weakness, numbness, and tingling.

Symptoms of Diabetes........

People can often have diabetes and be completely unaware. The main reason for this is that the symptoms, when seen on their own, seem harmless. However, the earlier diabetes is diagnosed the greater the chances are that serious complications, which can result from having diabetes, can be avoided.
Here is a list of the most common diabetes symptoms:

Frequent urination
Have you been going to the bathroom to urinate more often recently? Do you notice that you spend most of the day going to the toilet? When there is too much glucose (sugar) in your blood you will urinate more often. If your insulin is ineffective, or not there at all, your kidneys cannot filter the glucose back into the blood. The kidneys will take water from your blood in order to dilute the glucose - which in turn fills up your bladder. 


 

Disproportionate thirst 
If you are urinating more than usual, you will need to replace that lost liquid. You will be drinking more than usual. Have you been drinking more than usual lately?


 Intense hunger 
As the insulin in your blood is not working properly, or is not there at all, and your cells are not getting their energy, your body may react by trying to find more energy - food. You will become hungry. 


Weight gain 
This might be the result of the above symptom (intense hunger). 


 Unusual weight loss 
This is more common among people with Diabetes Type 1. As your body is not making insulin it will seek out another energy source (the cells aren't getting glucose). Muscle tissue and fat will be broken down for energy. As Type 1 is of a more sudden onset and Type 2 is much more gradual, weight loss is more noticeable with Type 1.

 

 Increased fatigue 
If your insulin is not working properly, or is not there at all, glucose will not be entering your cells and providing them with energy. This will make you feel tired and listless. 


 Blurred vision 
This can be caused by tissue being pulled from your eye lenses. This affects your eyes' ability to focus. With proper treatment this can be treated. There are severe cases where blindness or prolonged vision problems can occur


 Cuts and bruises don't heal properly or quickly 
Do you find cuts and bruises take a much longer time than usual to heal? When there is more sugar (glucose) in your body, its ability to heal can be undermined.


 More skin and/or yeast infections 
When there is more sugar in your body, its ability to recover from infections is affected. Women with diabetes find it especially difficult to recover from bladder and vaginal infections. 


 Sexual dysfunction among men 
If you are over 50 and experience frequent or constant sexual dysfunction (erectile dysfunction), it could be a symptom of diabetes. 

 Numbness or tingling, especially in your feet and hands 
If there is too much sugar in your body your nerves could become damaged, as could the tiny blood vessels that feed those nerves. You may experience tingling and/or numbness in your hands and feet.


 What is diabetes? What causes diabetes?

Diabetes (diabetes mellitus) is classed as a metabolism disorder. Metabolism refers to the way our bodies use digested food for energy and growth. Most of what we eat is broken down into glucose. Glucose is a form of sugar in the blood - it is the principal source of fuel for our bodies.

When our food is digested the glucose makes its way into our bloodstream. Our cells use the glucose for energy and growth. However, glucose cannot enter our cells without insulin being present - insulin makes it possible for our cells to take in the glucose.

Insulin is a hormone that is produced by the pancreas. After eating, the pancreas automatically releases an adequate quantity of insulin to move the glucose present in our blood into the cells, and lowers the blood sugar level.

A person with diabetes has a condition in which the quantity of glucose in the blood is too elevated (hyperglycemia). This is because the body either does not produce enough insulin, produces no insulin, or has cells that do not respond properly to the insulin the pancreas produces. This results in too much glucose building up in the blood. This excess blood glucose eventually passes out of the body in urine. So, even though the blood has plenty of glucose, the cells are not getting it for their essential energy and growth requirements.

Why is it called Diabetes Mellitus?

Diabetes comes from Greek, and it means a siphon. Aretus the Cappadocian, a Greek physician during the second century A.D., named the condition diabainein. He described patients who were passing too much water (polyuria) - like a siphon. The word became "diabetes" from the English adoption of the Medieval Latin diabetes.
In 1675 Thomas Willis added mellitus to the term, although it is commonly referred to simply as diabetes. Mel in Latin means honey; the urine and blood of people with diabetes has excess glucose, and glucose is sweet like honey. Diabetes mellitus could literally mean "siphoning off sweet water".
In ancient China people observed that ants would be attracted to some people's urine, because it was sweet. The term "Sweet Urine Disease" was coined.

There are three main types of diabetes:

Diabetes Type 1 - You produce no insulin at all.
Diabetes Type 2 - You don't produce enough insulin, or your insulin is not working properly.
Gestational Diabetes - You develop diabetes just during your pregnancy.
(World Health Organization)
Diabetes Types 1 & 2 are chronic medical conditions - this means that they are persistent and perpetual. Gestational Diabetes usually resolves itself after the birth of the child.

Treatment is effective and important

All types of diabetes are treatable, but Type 1 and Type 2 diabetes last a lifetime; there is no known cure. The patient receives regular insulin, which became medically available in 1921. The treatment for a patient with Type 1 is mainly injected insulin, plus some dietary and exercise adherence.

Patients with Type 2 are usually treated with tablets, exercise and a special diet, but sometimes insulin injections are also required.

If diabetes is not adequately controlled the patient has a significantly higher risk of developing complications, such as hypoglycemia, ketoacidosis, and nonketotic hypersosmolar coma. Longer term complications could be cardiovascular disease, retinal damage, chronic kidney failure, nerve damage, poor healing of wounds, gangrene on the feet which may lead to amputation, and erectile dysfunction. for more info>>>>
