Antibiotic treatment in patients with chronic low back pain and bone edema on MRI adjacent to a previously herniated disc or adjacent to a degenerated disc: a double-blind study where patients at random are offered antibiotics or placebo tablets without knowing which tablets they are given.

Phase 1
Conditions
A recent Danish study published during spring 2013 advances a remarkable cause and treatment with Amoxicillin for a selected sub-group of low back pain patients.The study was based upon a hypothesis that chronic low back pain may arise from a low-grade infection of the intervertebral disc by the anaerobic Proprione acne bacteria, resulting in pain and bone edema (Modic changes). The main scope of this RCT is to re-examine the effect of amoxicillin in this patient group.
