Back Pain Q & A

What back injuries commonly cause pain?

Back injuries commonly occur from sports activities (especially high-impact sports), stress caused by repetitive movements, car accidents, falls, and sudden, jarring, or twisting movements. You can also injure your back lifting something that’s too heavy or by using poor body mechanics when lifting.

The most common pain-causing back injuries are sprains, strains, a stinger or pinched nerve, fractured vertebrae, and slipped discs.

What degenerative conditions cause back pain?

Back injuries often overlap with degenerative conditions because an injury can directly cause or increase your risk of developing a chronic condition. Back pain may arise from numerous degenerative conditions, including:

Herniated and degenerated discs

Over the years, spinal discs dry out and weaken, which causes herniated discs and degenerative disc disease. A degenerated disc tends to flatten and lose its normal height. A herniated disc occurs when a weak outer layer lets the inner gel-like center of the disc leak out.


Osteoarthritis affects the spine’s facet joints and causes bone spurs that protrude into the spinal canal and pinch nerves.

Spinal stenosis

This condition occurs when the spinal canal narrows due to thickened ligaments, bone spurs, or a slipped, herniated, or degenerated disc.

How do interventional treatments relieve my back pain?

Interventional pain medicine is a specialized field that relieves pain by targeting the nerves that send pain signals to your brain. You only feel pain when your brain interprets information received from nerves. As Dr. Purswani administers treatments that stop nerve impulses, your brain doesn’t get the message, so your pain is relieved. He can also relieve your back pain by injecting steroids that significantly reduce inflammation around irritated nerves.

These are a few examples of interventional treatments for back pain:

  • Epidural injections: administered in the epidural space of the spine so pain-relieving medications can surround nerves
  • Medial branch nerve block: an injection to relieve facet joint pain
  • Radiofrequency ablation: radiofrequency energy is applied to nerves to block pain signals
  • Spinal cord stimulation: gentle electrical current is used to block or mask nerve signals

The interventional treatments offered by Dr. Purswani are all done in the office. Injections are administered using imaging to ensure precise placement of the medication.
