Choose the question first
An injection into a facet joint and a medial branch nerve block are not interchangeable labels. Ask whether the visit aims to relieve symptoms, test a suspected source, or decide whether radiofrequency ablation should be considered.
Lower-back pain can arise from several structures even when imaging shows facet wear. Ask the clinician to explain why this joint is the working target now.
Record meaningful change
Before the procedure, identify two or three everyday movements that reproduce the usual pain. Afterward, note both pain and function over the time window the team specifies. A vague report of feeling better provides less information than a timed activity record.
Bring details of pain with standing, extension, twisting, or other movements, but ask what competing diagnoses remain possible. Similar movements can provoke pain from more than one structure; the purpose of a block is to add evidence, not to replace an examination.
Understand uncertainty
Imaging can show joint changes without proving the joint causes pain. The clinician should explain the level chosen, the expected value of the test, risks and alternatives, and what an inconclusive result means.
Clarify whether a second diagnostic block, a different therapy, or a change in diagnosis would follow the first result. This is especially relevant when the effect is brief, mixed with procedure soreness, or hard to compare with an ordinary day.
Questions to ask
- What evidence points to a lumbar facet source?
- What precise injection or block is planned?
- How should I document activity during the assessment window?
