Examples of Paraesthesia

Meaning of Paresthesia

Kinship is classified as an irritative sensitivity disorder that presents with abnormal sensations without prior stimulation, such as tingling. This sensation tends to occur in the arms, hands, fingers, legs, and feet, however it can occur anywhere on the body. In most cases, this abnormal sensitivity is transitory, and we usually describe it as that some part of the body “has fallen asleep”.

Origin and manifestation

This sensation of the member asleep originates when we remain for a long time in the same position where there is pressure sustained by a nerve . The main example is if we sit for a long time with our legs crossed or rest with one arm or one hand under our head.

When this sensation manifests itself in a recurrent or chronic way, paresthesia can be linked to an injury that a nerve has suffered or with some pathology that can seriously affect any of the structures of the nervous system , both the central one, which is made up of the brain. and spinal cord, as well as peripheral, composed of all peripheral nerves

In this area, damage to nerves and nerve endings can be terminal or permanent, in the same way it can affect one branch of nerves or several. In case any of them are damaged, various problems arise that cause pain and difficulty in walking.

Examples of conditions

In the first place, we can mention the affections of the central nervous system (brain and spinal cord) and of the peripheral nervous system as consequences of paresthesia.

Among those that directly affect the central nervous system , it is worth highlighting the mini-transient ischemic attacks (CVA), cerebrovascular accident (CVA), encephalitis, transverse myelitis, cerebral aneurysm (it is a dilation or bulge in a brain artery) cerebral arteriovenous malformation, herniated discs, multiple sclerosis or seizures. There are also various types of brain tumors, of the spinal cord that can cause paresthesia.

Similarly, there are numerous infectious pathologies that are susceptible and can cause paresthesia, with variable involvement in different locations of the nervous system. Clear examples of this are: herpes zoster infection or shingles, lyme disease that is transmitted by ticks, syphilis, leprosy and HIV / AIDS.

Other little-known diseases, some of them hereditary, can also cause paresthesia.

Warning signs and treatments

Despite the fact that most of the time the tingling in the arms and legs is not associated with any pathology, it is necessary to visit the doctor in case of sudden paraesthesia or weakness, the numbness progressively expands to other regions of the body, it occurs shortness of breath, there is incontinence as a result of loss of bladder and bowel control, symptoms rapidly affect both parts of the body, sensation in the face and torso is lost, or half of the arm or leg sleeps complete.

Other reasons for alarms are also the alteration in the level of consciousness , speech problems or vision changes or that paresthesia occurs just after a blow to the back, neck or head.

The doctor will try to identify the disorder causing the paresthesia, and then prescribe the necessary treatment to treat or identify it.

In case the cause of the tingling is due to a pathology, it is necessary to keep it under control in order to stop the paresthesia or avoid its complication. For example, in case of diabetes, it is important to regulate the level of sugar in the blood with the help of a doctor. In the event that the trigger is a stroke or multiple sclerosis, medical monitoring and treatment of the condition is also of utmost importance.

If the symptom has created a syndrome of the carpal tunnel you can use a splint or surgical intervention. In the same way, in this case and in other similar ones, physical therapy exercises may be necessary to improve the affected area or increase the ability to mobilize it.
