Tingling hands, feet, or both is an extremely common and bothersome symptom. Such tingling can sometimes be benign and temporary. For example, it could result from pressure on nerves when your arm is crooked under your head as you fall asleep. Or it could be from pressure on nerves when you cross your legs to long. In either case, the ""pins and needles"" effect -- which is usually painless -- is soon relieved by removing the pressure that caused it. In many cases, however, tingling in the hands, feet, or both can be severe, episodic, or chronic. It also can accompany other symptoms. such as pain, itching, numbness, and muscle wasting. In such cases, tingling may be a sign of nerve damage, which can result from causes as varied as traumatic injuries or repetitive stress injuries, bacterial or viral infections, toxic exposures, and systemic diseases such as diabetes.Symptoms include intermittent or persistent numbness which starts gradually and wakes one up at night.
HOW IS TINGLING DIAGNOSED?
The health care provider may also ask questions to determine the risk for stroke, thyroid disease, or diabetes, as well as questions about work habits and medicines. Tests may include:
• Angiogram (a test that uses x-rays and a special dye to see inside the blood vessels)
• CT angiography
• CT scan of the head
• CT scan of the spine
• MRI of the head
• MRI of the spine
• Ultrasound of neck vessels to determine your risk for TIA or stroke
• Vascular ultrasound
• X-ray of the affected area
• Electromyography and nerve conduction studies to measure how your muscles respond to nerve stimulation
• Lumbar puncture (spinal tap) to rule out central nervous system disorders
• Cold stimulation test may be done to check for Raynaud phenomenon
