Diagnostic Medial Nerve Branch Nerve Injection
Patients with increasing arthritis in the facet joints and patients with lower back pain can seek diagnosis and treatment with a medial nerve block, administered with an injection of local anesthetic and sometimes a steroid. With a medial nerve branch block, the injection is made outside the joint near the nerve. The results of the treatment can vary. If pain returns, the length of time relief was experienced and how the pain returns can be used in diagnosis to tell the doctor more about how to proceed with further treatment. Blocks are treatments that can be repeated if benefits are derived.
