What Actually Happens During a Spinal Decompression Session?

If you've been dealing with back pain, a disc injury, or sciatica, chances are someone has mentioned spinal decompression therapy. But if you've never experienced it, the concept can feel a bit vague — or even intimidating. What does it actually involve? Is it uncomfortable? How long does it take?

Here's a straightforward, honest walkthrough of what you can expect during a session at Complete City Health.

First, a Quick Word on Why It Works — Your spinal discs are like cushions between each vertebra. When they bulge, herniate, or degenerate, they can press on nearby nerves and cause pain. The goal of spinal decompression is to gently create space between the vertebrae, reduce pressure on the disc, and allow oxygen and nutrients to flow back in.

What Happens When You Arrive — We start with a conversation about your history, symptoms, and any imaging you've had. The angle of traction, force, and duration are all adjusted for your specific situation.

What the Session Feels Like — You lie fully clothed on a motorised table. A padded harness is fitted around your hips (or neck for cervical treatment). The table applies a gentle, rhythmic pulling force. Most patients describe it as a mild, pleasant stretch. No cracking, no twisting. Many people fall asleep.

How Long Does It Take? — 20–30 minutes per session. A typical course is 6–12 sessions over a few weeks, with regular check-ins to track progress.

What to Expect Afterwards — Most people feel fine immediately. You can go about your day normally. Mild muscle soreness in the first day or two is occasionally normal, and settles quickly.
