Although interventional procedures should be used cautiously in the setting of chronic pain, there is a role for a variety of injections to facilitate a patient's overall rehabilitation program. There are many resources available, including a prior issue of Physical Medicine and Rehabilitation Clinics of North America, which discuss the more conventional spinal injections. The focus of this article is on lesser-known injection options for treating chronic pain. The authors separately discuss trigger point injections, regenerative injections (prolotherapy), and injections using botulin toxins.
