Lower back pain can come from the facet joints or from a disc, and the two often feel different. Facet joint pain tends to sit in the back, feel like a deep ache, and get worse when you lean backward or twist. Disc pain more often worsens when you bend forward, sit for long periods, or lift.
If you feel your pain flare when you arch your back or stand for a while, and ease a little when you sit or bend forward, that pattern leans toward the facet joints. These small joints run along the back of your spine and can become irritated and inflamed.
If you feel pain shooting down your leg with tingling or numbness, that points more toward a disc pressing on a nerve. Facet joint pain usually stays local in the back and may spread into the buttock or upper thigh, but not typically far down the leg.
These patterns are clues, not proof. Discs and facet joints sit close together, and many people have some wear in both. This is why an exam and imaging come first, and sometimes a diagnostic block is used to confirm the source.
A lumbar facet joint injection places anti inflammatory medicine into or near the joint. It can reduce pain and also help confirm the joint as the source based on how much relief you feel.
If you feel like your pain matches the facet pattern, mention the specific movements that trigger it. Telling your specialist exactly which positions hurt and where the pain sits helps them decide whether your facet joints are the likely cause and whether an injection makes sense.
