This might be a skin condition you might want to get medically checked out called peripheral neuropathy .
This info is copied and pasted.
Peripheral neuropathy refers to the conditions that result when nerves that carry messages to and from the
brain and spinal cord from and to the rest of the body are damaged or diseased.
The peripheral nerves make up an intricate network that connects the
brain and spinal cord to the muscles,
skin, and internal organs. Peripheral nerves come out of the spinal cord and are arranged along lines in the body called
dermatomes. Typically, damage to a nerve will affect one or more dermatomes, which can be tracked to specific areas of the body. Damage to these nerves interrupts communication between the
brain and other parts of the body and can impair muscle movement, prevent normal sensation in the arms and legs, and
cause pain.
Types of Peripheral Neuropathy
There are several different kinds of peripheral neuropathies that stem from a variety of causes. They range from
carpal tunnel syndrome (a traumatic injury common after chronic repetitive use of the hands and wrists, such as with computer use) to
nerve damage linked to
diabetes.
As a group, peripheral neuropathies are common, especially among people over the age of 55. All together, the conditions affect 3% to 4% of people in this group.
Neuropathies are typically classified according to the problems they cause or what is at the root of the damage. There also are terms that express how extensively the nerves have been damaged.
Mononeuropathy
Damage to a single peripheral nerve is called mononeuropathy. Physical injury or trauma such as from an accident is the most common cause. Prolonged pressure on a nerve, caused by extended periods of being sedentary (such as sitting in a wheelchair or lying in bed), or continuous, repetitive motions, can trigger a mononeuropathy.
