Hemp is an experience in how.

As the saying goes: sleepy in spring, sleepy in autumn and sleepy in summer. If you add some hibernation behaviors of [great gods], you will basically fall asleep this year.

I think everyone has had the experience of waking up from an uncomfortable [nap] and preparing to wipe off the clear pool of saliva pasted on the table top. Suddenly, I feel my [hemp claws], or my hands, or my legs and feet, so quietly [hemp] up.

This feeling is like hundreds of ants standing still on their skin, making people feel uncomfortable scratching their hearts and livers.

[Ma] Is it a what situation?

As mentioned above, when we sleep in an inappropriate posture, [hemp] will appear. At this time, we only need to change our posture and move slightly, and this feeling will soon disappear.

Have you ever had such an experience that when you accidentally touch a magical place behind your elbow, you will have an indescribable acid straightening through our entire arm. That is actually touching [ulnar nerve], commonly known as [hemp tendon]. Don’t panic, in a few seconds, this acid will disappear without a trace.

There are also several kinds of exotic [hemp], such as when watching horror movies [scalp pins and needles with fear]; When eating hot pot, even your tongue and lips [hemp]; After some surgical incisions heal, if you touch them on the scar, you will also feel hemp and wood.

But after all, these common [hemp], in summary, this is not a thing.

Those who need to be alerted to

In addition to the above-mentioned hemp, which is not a matter, there are actually many situations that need to arouse people’s vigilance, because it may be the symptoms of a certain disease. The most important characteristic of hemp in these situations is that it does not return to normal so quickly.

As a moral and responsible medical worker, let me point out some common disease names from head to toe.

Step 1 Head and Face

If the head and face are numb somewhere, removing the [herpes simplex virus infection] at the corners of the mouth, that is, the early stage of [aphtha], there may be a feeling of numbness, or there may be a problem with the sensory nerves on the head or face.

If these nerves are inflamed or oppressed by tumors, the areas they are responsible for will feel numbness. At this time, you should go to neurology or neurosurgery.

Nerves that may cause problems include the greater occipital nerve and the lesser occipital nerve in the back of the head, the greater auricular nerve under the ear, and the trigeminal nerve responsible for facial sensation. Sometimes there are pathological changes in the brain, which can also lead to numbness in the head or face.

2. Body, medically called [trunk]

There are few opportunities for hemp in the body. One of the relatively common diseases is herpes zoster, which not only makes people feel painful, but also may make people feel hemp. It feels like an area of hemp, mostly on one side. This disease can be solved by dermatology department.

If most of the body’s sensation is decreased or painful, and even hands and feet have problems, then you need to go to neurology or neurosurgery to further determine the cause.

3. Neck and limbs

(1) Cervical spondylosis: One of the most common causes is that besides neck pain and discomfort, many patients may also feel numbness in the skin radiating to their shoulders, arms and even hands.

(2) Lumbar disc herniation: It is as famous as cervical spondylosis. Generally speaking, this disease is leg pain, but there are also many symptoms of skin numbness in legs, even soles and instep, and even some people have numbness in [crotch], which is medically called [sellar sensory disturbance]. At this time, cauda equina nerve may be affected.

(3) Spinal canal stenosis caused by various reasons: Patients may have abnormal sensation or movement of lower limbs. The typical situation is that patients feel numbness and weakness of lower limbs after walking for a period of time and can recover after a short rest. Repeated, we call this phenomenon [intermittent claudication].

When the above neck, waist or spine problems occur, you should go to the orthopaedic department in time.

(4) Diabetes: The part that wears gloves and socks at ordinary times has left and right symmetrical numbness; If you drink a lot of water, go to the toilet frequently, eat a lot but do not gain weight at the same time, you should go to the endocrinology department to check your blood sugar as soon as possible.

(5) Peripheral nerve injury: It is possible that armpits, wrists and other positions are injured, and the corresponding areas will feel numb, and some will have hand and foot movement problems, which can be seen in hand and foot surgery or orthopaedics.

4. Other

The spinal cord is actually made up of many nerves, which are specially responsible for sensation. Therefore, if something goes wrong with the spinal cord, it is possible to feel numbness at the corresponding position.

There are also some diseases that can also cause numbness. The relatively common ones include:

    [Hypoparathyroidism] in endocrinology department will cause numbness of mouth and lips due to calcium deficiency. [Aldosteronism] in endocrinology department will cause numbness due to spinal cord damage. Rheumatology [systemic lupus erythematosus], can cause spinal cord diseases, leading to limb numbness; Rheumatology [rheumatoid arthritis], resulting in nerve compression and numbness; Arteriosclerosis in cardiology; Vasculitis in vascular surgery can lead to numbness of hands and feet. Organophosphorus poisoning can also cause [numbness].

However, the above is still only the tip of the iceberg. It is estimated that the story about [Ma] cannot be finished in a book. It is hoped that everyone can be alert to [Ma] that has not been relieved for a long time and go to the hospital to treat the corresponding diseases as soon as possible.

Why do you feel [hemp]?

This is a very big problem. In fact, [hemp] is not one of our standard senses at all. All our skin can feel is [pressure], [touch], [pain] and [temperature]. The so-called [hemp] is actually a signal of [discomfort] in our sensory nerves.

If the nerve is directly damaged, such as broken, suppressed or infected, and the feeling cannot be normally transmitted to the brain, we will feel [hemp], such as [peripheral nerve injury], tumor compression, or neuritis.

It is also possible that the nerve [malnutrition], for example, the blood vessels supporting it are suppressed by the sleeping posture with myriad manners, and then the corresponding nerve will protest and show numbness; Some internal diseases cause peripheral circulation disorders of hands and feet, as well as arteriosclerosis and vasculitis of blood vessels themselves, which make blood flow obstructed and cause numbness.

Why is hemp not pain?

In fact, this principle is similar to [hemp is not itching]. Because the two are different ways! [Ma] The reception of this kind of feeling does not need to be obtained from [nociceptors] like [pain]. Since you do not take that road, you will naturally not be able to form that kind of feeling.

[Ma] This matter can be large or small, depending on the situation, but if there is an abnormal and extremely long-term [Ma], the best way is to cure the disease!
