'Abnormal nerve sensations such as pins-and-needles, tingling, burning, prickling or similar feelings are all known as "paresthesias". Some cases are severe enough to be considered painful. Paresthesias usually result from nerve damage due to pressure, entrapment, or nerve diseases. Continued nerve damage can lead to finger numbness and permanent loss of feeling. Any abnormal sensation needs medical investigation.
Distinction as to which fingers are tingling is important to diagnosis. The main fingers are more likely to be affected by conditions such as carpal tunnel syndrome. The 4th and 5th fingers are affected by the ulnar nerve, which can be interrupted by pressure at the elbow or the chest area (e.g. thoracid outlet syndrome).
Parethesias in the hands and fingers can also be caused by broader diseases such as peripheral neuropathy (more common in the feet but hands can be affected) and various others. Correct diagnosis of the causes of finger paresthesias is important and treatment can often reverse the damage. '

Consult your doctor to find out the cause in your case.
For the past two weeks I have been feeling tingling on my hands and toes on and off during the day. Sometimes my right arm is numb during my sleep even though I didn't put any pressure on it. My legs are also in pain for no reason. Sometimes I feel pain on my laps, on my calves. I feel pain on my feet when I walk for an hour now. I used to walk for a few hours and still don't feel tired. The upper bottom of my feet are swollen from walking. I am really worried about the symptoms that I am getting. Can anyone explain what these sypmtoms indicate? Thanks very much!
