why is my hand numb and tingling

I have been suffering over the last four days with a tingling and numbness in the fingertips of my right hand. I am right handed. My wife wants me to go to the doctor. She thinks it's something to do with poor circulation. The condition is more uncomfortable than painful but nothing I do seems to make it go away. Can you give me any suggestions as to what might be the problem? Sorry to hear you have this problem, but it's very unlikely to be anything to do with your circulation, as it is so well localised to your right hand. Another thing people worry about with these sort of symptoms is a, but I think that too is very unlikely. With the symptom of numbness as well as tingling it sounds much more as if this is a nerve entrapment. That means that somewhere along the line of the nerves that supply this part of your hand, there is some pressure on a nerve. The neck is a possibility because the nerves that go to your hand exit the spine in the neck and travel down the arm into the fingers.

A bit of wear and tear, or even a bit if a twist to the ligaments here could cause pressure on the nerves that would then be felt as tingling and numbness in the fingers. The other likely possibility is pressure in the wrist. The nerves to the fingers go through a small tunnel at the wrist to get into the hand called the carpal tunnel. Pressure here will produce similar symptoms. Usually it is the middle fingers that are most affected. It can be worse at night and cause pain or discomfort that may wake you, or the hand may feel particularly numb and heavy first thing in the morning. This condition is called. There are usually no serious reasons for these symptoms. Nevertheless, it would be sensible to tell your doctor about them, so he or she can confirm the likely cause and advise you about treatment if that becomes necessary. This may be the case if the symptoms do not soon settle on their own. Last updated 29. 09. 2014
In addition to numbness, compression neuropathy can cause weak or twitchy muscles.

Compression neuropathy is pressure on a nerve (Figure 1). The pressure may come from an injury, thickened muscles, enlarged blood vessels, ganglion cysts, etc. Types include: Ulnar nerve compression at the wrist : This causes numbness and tingling of the little finger, part of the ring finger, and in the palm on the little finger side. Ulnar nerve compression at the elbow : This causes not only the numbness noted above but also numbness on the back of the hand on the pinky side. Pressure on the radial nerve in the forearm or above the wrist : This can cause numbness over the back of the thumb, the index finger, and the web between these two fingers. Median nerve compression at the elbow : This can cause numbness not only in the same area as in carpal tunnel syndrome but also in the palm at the base of the thumb. Pressure on nerves in the neck (Figures 2-3) : This can be caused by arthritis, diseases, infections, tumors, blood vessel abnormalities and other conditions of the spinal cord.

In addition to numbness, symptoms include weak muscles and decreased reflexes in the arm and forearm, and even the legs. Sometimes, a nerve may suffer from pressure at more than one area. This is called double crush. Pressure on a nerve may require surgery to get relief. With this condition, there may or may not be pain, and the numbness is often constant and very general in location. Diabetes, alcoholism, and old age are common known causes of neuropathy. Poisoning from metals and industrial compounds are also possible causes. Millions of Americans suffer from this condition, which can last for years or indefinitely. People with fibromyalgia have been shown to be more likely than others to develop carpal tunnel syndrome and may seek surgical treatment, which can only help carpal tunnel syndrome if it exists with fibromyalgia.

People with this condition have persistent pain, frequently in many areas throughout the body, as well as fatigue, headaches, bowel problems, depression, sleep problems and other generalized symptoms. This is another condition known to cause numbness in the hand. It has some symptoms similar to fibromyalgia, specifically numb hands and numb forearms, often with aches and pain. Although the symptoms may be felt in the hands, the muscles causing the problems are usually those in the neck and shoulder region. The symptoms are usually stiffness and may be associated with frequent headaches. There is no hand surgery to correct or improve symptoms with this condition. Certain medications, such as cancer treatment drugs, are known to cause numbness and tingling in the hands. Some of these cause temporary numbness that goes away after completion of the chemotherapy treatment. Others may cause permanent numbness. Nutritional deficiencies, such as vitamin B1 deficiency
