tingling sensation in left arm, hand and fingers
I have a tingling sensation in my left arm, hand and fingers when I rest my arm in a certain position. Ex. When I rest my arm on a desk or table. It's really beginning to bother me. I'm not sure if it is a pinched nerve or something else. Anyone have any suggestions?

Hi,

'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. '

'# Other medical conditions, including:

    * Carpal tunnel syndrome
    * Diabetes
    * Migraines
    * Multiple sclerosis
    * Seizures
    * Stroke
    * Transient ischemic attack (TIA)
    * Underactive thyroid

# Abnormal levels of calcium, potassium, or sodium in your body
# A lack of vitamin B12 or other vitamin
# Certain medications
# Toxic action on nerves, such as that from lead, alcohol, or tobacco
# Radiation therapy'
