The sural nerve branches from the tibial and common fibular nerves and is responsible for feeling on the outside of the foot and the small toe. The medial and lateral plantar nerves are the two largest nerves in the bottom of the foot.

In human anatomy, the dorsalis pedis artery (dorsal artery of foot), is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It is located 1/3 from medial malleolus. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery.

Sciatic nerve The sciatic nerves branches from your lower back through your hips and buttocks and down each leg. Sciatica refers to pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg.

As a region, the ankle is found at the junction of the leg and the foot. It extends downwards (distally) from the narrowest point of the lower leg and includes the parts of the foot closer to the body (proximal) to the heel and upper surface (dorsum) of the foot.

In the neurons that make up the nerves running from the spinal cord to your toes, the axons can be as long as three feet! Longer axons are usually covered with a myelin sheath, a series of fatty cells which have wrapped around an axon many times.

If you have Sciatica, it means that you have nerve induced pain from the lower back. At times, Sciatica can be present in patients who also have Plantar Fasciitis (heel pain). Sciatica is a pinching or irritation of the nerve that occurs in your lower spine. This often sends a shooting pain down your legs and feet.

Foot numbness is usually due to a lack of blood supply to an area or nerve damage. Foot numbness can result from infection, inflammation, trauma, malignancy, and other abnormal processes, although a numb foot usually indicates nerve damage or disease.

['The peroneal muscles (peroneus longus and peroneus brevis), on the outside edge of the ankle and foot. ... ', 'The calf muscles (gastrocnemius and soleus), which are connected to the calcaneus via the Achilles tendon.']

Peripheral neuropathy is as its name states—it affects only the nerves in the periphery of the body. That is, those that are outside the brain and spinal cord. Typically, these would be the ones in the feet, hands, and lower legs. Meanwhile, MS deals with the nerves of the central nervous system.

Odd spontaneous sensations are often the initial symptom of a peripheral neuropathy. Patients with polyneuropathies often describe the sensation that a thin layer or film is surrounding their toes or the soles of their feet. It may also feel as though something is stuck between the toes.

Can Diabetes Make My Feet Hurt? While the danger of numbness and loss of sensation from peripheral neuropathy is the biggest threat to diabetes sufferers, feet with sensation (that can feel pain!) are no picnic either. Diabetes can contribute to painful feet, especially heel pain from plantar fasciitis.

It's caused by inflammation, overuse, or injury to the plantar fascia. The plantar fascia is the ligament that connects the front of your foot to your heel. It's often seen in runners, but it can also occur in nonrunners. If you have plantar fasciitis, you may feel pain and stiffness in the heel and arch.

Causes. Injury, overuse or conditions causing inflammation involving any of the bones, ligaments or tendons in the foot can cause foot pain. Arthritis is a common cause of foot pain. Injury to the nerves of the feet may result in intense burning pain, numbness or tingling (peripheral neuropathy).

A heel spur is a calcium deposit that forms a bony protrusion along the plantar fascia. In contrast, plantar fasciitis is a condition where the plantar fascia gets irritated and swollen, which causes pain in the heel. Doctors often describe the plantar fascia as a bowstring-like tissue.

Causes of Foot Numbness The most common cause of peripheral neuropathy or foot numbness in the US is diabetes. Other things such as thyroid disorders, rheumatoid arthritis, alcohol use, chemotherapy and other drugs may cause it as well.

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

Neuropathy: Low levels of thyroid hormone can result in nerve damage, called neuropathy,7﻿ characterized by tingling and numbness in the extremities. A painful foot condition known as plantar fasciitis may also develop in your feet, caused by edema (fluid buildup) around the nerves.
