Most people are well aware what the sensation of tingling and numbness in legs feels like. More popularly known as the 'legs falling asleep', this problem stems from a variety of different causes. Most of these causes can be attributed to the field of neurology, which studies and predicts the actions of the nerves that constitute the nervous system of the body. There are certain conditions that affect these nerves, and thus, produce the sensation in legs and other parts of the body.
Tingling feels like a bunch of needles simultaneously pricking the body, and is usually accompanied with the feeling of numbness. We often find that sitting in a particular position leads to it, or even the feeling of numbness, in certain parts of the body. The hands, the feet, the arms, and the legs are the primary parts that get afflicted by this. The sensation is also caused by a lack of blood to the legs. Sitting in a particular position will hinder the blood flow there, and this induces numbness and prickling sensation in the legs.
In usual cases, this is a condition that does not require serious medical supervision. Just by changing your position, or by straightening out your legs and rubbing them, you can get rid of this annoying sensation. However, if the tingling continues after that and refuses to go away, or if it goes away but keeps returning, then maybe you need to go visit a doctor as it may just be a pinched nerve or some other serious problem. Following are some common possible causes of the problem:
- Sitting in an awkward position, that limits and hinders the flow of blood to some part of the body.
- Sitting in the same position for a very long time.
- A serious case of nerve damage, as a result of an injury sustained by the nerve.
- Spinal nerves receiving excessive pressure, like in the condition of a herniated disk.
- Nerve damage due to toxic substances that are consumed by the body from external sources.
- Side effects of some medications or therapies.
- Calcium, potassium, or sodium being present in your body at either extremely high levels or very low levels.
- It may also be due to carpal tunnel syndrome (CTS).
- As a result of some other medical conditions like diabetes, multiple sclerosis, seizures, strokes, underactive thyroids, or Raynaud's Phenomenon.
Visiting a Doctor
As mentioned earlier, the effects of tingling can be shaken off fairly easily by moving and rubbing the legs, but if the frequency and the intensity is alarming and shockingly regular, then it is necessary to seek medical help. The doctor can then accurately ascertain if there is any nerve damage, or if the phenomenon is occurring due to the onset of some other serious medical condition. He will carry out a complete and thorough analysis of the nerves in the afflicted body part and even in the neighboring and surrounding parts. This will help him diagnose the problem and prescribe you the course of action to be taken in order to fix it.
