Tingling in the hands and fingers is an annoying problem to have – usually, it’s nothing serious, but sometimes it might be cause for concern. Tingling in the hands may be caused by hypothyroidism or a pressed nerve in the body, but if it comes and goes without an apparent problem, it means that there’s something wrong in your body. Today we’re going to show you what the tingling in the limbs means and what the possible causes may be.
Tingling in the hands and feet is a common problem – most of the time, it’s nothing to concern yourself with, but sometimes it may indicate bigger problems. The tingling may last for a while and disappear until the next episode and may be accompanied by pain, reduced sensation or itching. In these cases, it is probably related to damaged nerves as a result of certain underlying conditions. This type of nerve damage is called peripheral neuropathy and occurs in the remote parts of the brain and spinal cord nerve endings.
Peripheral neuropathy affects the hands, fingers, feet and toes. There are more than 100 types of it, and the symptoms progress over time. It can reduce your mobility, and can only be resolved with medical help. As with most diseases, it’s better to prevent the disease than treat it later.
The most common causes of tingling in the limbs is difficult to determine and depends on numerous factors. About 30% of the cases are associated with diabetes, while another 30% of cases have no obvious cause and is referred to idiopathic peripheral neuropathy. The remaining 40% of cases may be caused by a variety of conditions. Before we present the list of causes, we just need to say that your tingling may not be related to any of these conditions – sometimes, the tingling you’re experiencing is caused by a muscle twitch or occurs as a result of some minor movement. With this out of the way, here’s the list of underlying condition that might be causing tingling in your arms and legs:
PINCHED NERVES IN THE NECK OR BACK
If your arms are tingling and the pain reaches to the neck, feet or back, it might be caused by a compressed or pinched nerve. A pinched nerve may occur due to injury or incorrect posture or an inflammatory disease such as arthritis. Depending on the severity, your doctor may put you on prescription medications that will soothe the over-stimulation of nerves in the brain. The therapy will control the symptoms effectively, but you’ll still need physical therapy to treat the pinched nerve.
LACK OF VITAMIN B12
Vitamin B12 deficiency can definitely cause tingling in the hands of feet, especially if its combined with lethargy and fatigue. The levels of vitamin B12 in the body can be detected with a special test – if you’re lacking it, you’ll need to increase its intake by taking dietary supplements. Doctors might give you vitamin B12 injections which will help the nervous system perform properly. The vitamin can also be found in foods of animal origin.
CARPAL TUNNEL SYNDROME
Carpal tunnel syndrome may also cause tingling in the hands. The syndrome is caused by a twisted nerve in the wrist, which can be detected by electromyography test. If you’re suffering from it, you need to stop doing repetitive motions with your hands in order to relieve the condition. Some extreme cases may require surgery.
NECK OR BACK STENOSIS
Neck od back stenosis can put extra pressure on the nerves and spinal cord and cause tingling in the hands or feet. If you’re suspecting it, visit a doctor who can take scans of your neck and back and properly diagnose and treat the problem.
High blood sugar levels are usually caused by poor diet which can seriously affect your nervous system and cause tingling in the hands or feet. If left untreated for a longer period, the high blood sugar levels may lead to diabetes, a serious disease which requires life-long treatment. You should always keep your glucose levels in check – not just to avoid tingling in the hands or feet, but to keep your overall health in check as well. In general, diabetes requires major diet and lifestyle changes.
If the tingling in your hands and feet is accompanied by unexplained weight gain, dry skin, hair loss and fatigue, it may be caused by hypothyroidism. An underactive thyroid is easy to detect with a simple blood test, and may require taking synthetic thyroid hormone for treatment.
MULTIPLE SCLEROSIS (MS)
If you’re suffering from tingling in your hands and feet along with awkward and uncontrolled movement and bladder problems, it may be caused by multiple sclerosis. If you’re suspecting that this is the case, get an MRI to make sure you detect the disease on time.
This disease manifests through hypersensitivity to light, sound and pain and is more common in women than men. One of the main symptoms of fibromyalgia is tingling in the muscles – if it’s accompanied by pain, memory loss and fatigue, you should visit a doctor immediately.
Sciatica is a term which describes an irritated vagus nerve which runs from the lower back down to the foot. The condition can cause leg pain and tingling in the toes, and may progress to numbness in the hamstrings and feet.
Hormonal changes during pregnancy and might cause tingling in the hands, feet or toes. The fluid accumulation during this period may cause extra pressure on your nerves and cause the tingling. Hormonal changes may also take place during puberty or menopause. In order to restore the hormonal balance, you should consume a healthy diet and start taking dietary supplements.
FEAR AND HYPERVENTILATION
Fear and hyperventilation might cause tingling in your hands, feet and lips. If this is the case, we suggest talking to your doctor in order to find the best possible solution for you.
