"My hands are numb and I feel tingling down to my elbows" — this is a description I hear in the office several times a week. Tingling in your hands or feet can be harmless, for example after sitting in the same position for too long. But when it occurs regularly, for no apparent reason, or is accompanied by weakness, it's a signal worth taking seriously.
What tingling actually is
Tingling, numbness, and a "pins and needles" sensation are medically known as paresthesias. They occur when the transmission of signals through nerves is disrupted in some way — whether by pressure, inflammation, damage, or a lack of certain substances in the body. You can think of the nervous system as a network of electrical wires: when there is a "bad connection" somewhere, the signal doesn't pass through clearly and the tingling or numbness occurs.
It is important to note that tingling is not a disease in itself, but a symptom that indicates that something is affecting your nerves.
The most common causes I encounter in practice
In my office, the most common causes of tingling are nerve compression—for example, carpal tunnel syndrome in people who work a lot at a computer, or pressure on nerves in the cervical spine. But the causes can be less obvious: a vitamin B12 deficiency (which is crucial for nerve fiber health), diabetic neuropathy, and even long-term stress that keeps the muscles in the neck and shoulders in a constant state of spasm.
Sometimes patients come in worried that their tingling sensations mean something very serious. In most cases, with thorough diagnostics, we can clarify the situation and find a specific cause.
EMNG scan — what to expect
One of the most important diagnostic tools for tingling is EMNG (electroneuromyography). This is a test that measures the speed of nerve conduction and muscle function. The procedure involves mild electrical impulses that can be uncomfortable, but are not painful. The test takes about twenty minutes and provides precise information about whether a nerve is damaged, where, and to what extent.
I always tell patients not to be afraid of this test — the information it gives us is invaluable for an accurate treatment plan.
What can we do?
Depending on the cause, the approach varies. In the case of nerve compression, manual therapy can help relieve the pressure on the nerve. If the cause is in the cervical spine, a combination of neurological therapy and targeted spinal manipulation often brings improvement.
A nutritional analysis is a step I never skip. A deficiency in vitamins B12, B6, folic acid, or magnesium can directly affect nerve health. When we replenish what the body is lacking, the tingling often decreases or goes away completely. Acupuncture can also help, especially with tingling related to tension and stress.
Practical advice you can apply immediately
Pay attention to the situations in which the tingling occurs: is it always in the same position, at the same time of day, after a certain activity? Write it down. Also, if you work at a computer, take a short break every 45 minutes — stand up, stretch your neck and shoulders, shake your arms. These simple habits can significantly reduce pressure on the nerves.
If the tingling doesn't go away, comes back, or spreads, don't wait for it to "fix itself." Call for a consultation — usually, an examination and an EMG are enough to figure out what's going on and what we can do.
