How long does a cervical facet joint injection take to work?

A cervical facet joint injection often has two stages of relief. Many people feel some numbness within the first hour from the local anesthetic, and then a return of pain as that wears off. The steroid portion, which reduces inflammation, usually starts working over the next two to five days.

If you feel great right after and then sore again by that evening, that is expected. The early relief comes from the numbing medicine, not the steroid. The steroid needs time to lower the inflammation in and around the joint.

Full effect is usually clear within a week to ten days. If you feel a meaningful drop in your neck pain by then, the injection did its job. How long that relief lasts varies widely, from several weeks to several months, and differs from person to person.

It helps to keep a simple record. Note your pain level before the injection and each day after. If you feel your usual flare when turning your head or looking up start to ease, that is a good sign the target was correct.

Some soreness at the injection site for a day or two is common. If you feel a temporary bump in pain right after, ice and rest usually settle it.

If the relief is strong but does not last as long as you would like, that information is useful. It can point your specialist toward a longer lasting option, such as a procedure that calms the small nerves feeding the joint. Bring your notes to your follow up so the plan can be adjusted to what your body actually did.
