A tingling sensation in the hands and fingers usually happens due to damage to nerves that provide sensation to the fingers. At times, there may be lack of blood supply to some areas of the hand which may cause tingling in the hand. The tingling sensation can have a number of causes, including Carpal tunnel syndrome, Ulnar tunnel syndrome, an Ulnar nerve compression in the Guyon canal of the wrist, Thoracic outlet syndrome. Sometimes, systemic diseases such as hypothyroidism, multiple sclerosis, amyloidosis, vascular diseases, or vitamin B12 deficiency can also cause tingling in hand.
Some other common causes for tingling in hands and fingers include:
- Autoimmune Diseases – like chronic inflammatory demyelinating polyneuropathy, Guillain-Barre syndrome, lupus, and rheumatoid arthritis.
- Inherited Disorder – especially those that have sensory and motor symptoms, like Charcot-Marie-Tooth disease
- Alcohol and other Toxins – including heavy metals like lead, arsenic, mercury, and thallium, and some industrial and environmental chemicals. Too much alcohol consumption can also cause nerve damage.
If left untreated, such tingling issues can lead to weakness of a certain group of muscles or even paralysis. Your hand specialist will conduct a physical examination, and take an extensive medical history that will address your symptoms, work and home environment, sleep affection, social habits and exposure to toxins.
Some of the tests your hand care specialist may suggest are:
- Electrophysiological studies are computer aided tests which help in assessing the electrical activity of the nerves and the muscles. An ElectroMyoGraphy (EMG) test is done to check the electrical activity of your muscles.
NCV, or Nerve Conduction Velocity assesses the status of the nerve.
- Ultrasonography test is done to detect the size of the nerve among several other findings.
- A variety of blood tests, to test for diabetes, vitamin deficiency, kidney or liver dysfunctions, or problems with the immune system may sometimes be done.
Rarely, some additional tests may include:
- Computed Tomography (CT)
- Magnetic Resonance Imaging (MRI)
- Nerve Biopsy
- Skin Biopsy to have a look at nerve endings
Most of the acquired diseases can be treated successfully. Diabetic neuropathy may be kept in check keeping a good control of diabetes. Similarly, vitamin supplements can help those with peripheral neuropathy arising from vitamin deficiencies.
Some common lifestyle recommendations from most doctors would be to keep your weight in check, avoid exposure to toxins, follow a supervised exercise program, keep a balanced diet, and to avoid or at least limit alcohol intake. Another very common recommendation would include giving up on smoking, which would otherwise hamper blood flow in blood vessels that provide nutrients to the peripheral nerves.
A successful treatment of tingling issues involves an accurate diagnosis of the causes. It has often been noted that the primary care physician makes a diagnosis of cervical spondylosis as the cause of tingling. This is rarely the case. The tingling generally occurs due to a compression of the nerves, and the cervical spondylosis is simply a coincidental finding.
CARPAL TUNNEL SYNDROME. In the initial stage of treatment for tingling, you may require a support for your wrist, called a cock-up splint. This would be followed up by an injection of a single low dose steroid. Only if these procedures fail, your hand specialist would move on to a minor surgery to eliminate pressure on the compressed nerve.
Tingling and numbness in the hand are common, and can have any number of treatments. For the best nerve injury treatment, tingling in hand, carpal tunnel syndrome, nerve compression, diabetic neuropathy treatment, please call 98220 31140 and fix an appointment.
The essence of examination and tests is to find out the exact location of the site of nerve compression and eliminate it.
