Pinched Nerve

Your spinal cord consists of delicate nerves that allow the brain and body to communicate. When pressure pinches one of your spinal nerves, it can interfere with the messages sent to your legs. As a result, you can feel pain, tingling or numbness in one or both of your legs. Pinched nerves need immediate treatment to avoid long-term problems.


Sciatica occurs as a result of a pinched spinal nerve root. A nerve called the sciatic nerve runs down your lower back and legs, and it affects both these areas when compressed. Pain from sciatica usually affects only one side of your body and radiates from your lower back to the back of the leg.

Herniated Disc

The spine has individual bones called vertebrae that are cushioned with soft discs. When a disc undergoes too much pressure, its soft interior can push through its exterior wall. While some people with herniated discs feel no symptoms, others experience numbness or weakness in an arm or leg. A herniated disc may also cause severe pain.

Spinal Stenosis

Spinal stenosis causes the bone around the spinal cord to narrow, putting extra pressure on the nerves. Age, arthritis, injuries, disc problems and other issues can result in the spine narrowing. When the bone presses on certain nerves, you can experience sciatica or other forms of nerve pain in your legs.

Foraminal Stenosis

The nerves in your back travel through entrances in the vertebrae called foramina. Multiple issues can result in these passages narrowing and pressing on the inside nerves, which is known as foraminal stenosis. Foraminal stenosis in the lower back vertebrae create symptoms such as numbness in the legs, buttocks and feet.


Spondylolisthesis occurs when one of your vertebrae moves out of place. Patients of any age can experience this condition, which can occur to various degrees. The misaligned vertebra puts pressure on your nerves, resulting in back and leg pain. It can also create numbness in one or both legs.

Sacroiliac (SI) Joint Dysfunction

The sacroiliac (SI) joint is located where your pelvis and spine meet. When the SI joint becomes misaligned, you can feel pain, tingling and numbness in your legs and lower back. SI joint dysfunction often grows more severe over time, making it imperative to get treatment right away.
