The purpose of this study is to learn if paravertebral block (PVB) will reduce chronic pain after surgery. Our hypothesis is that chronic pain from breast surgery as a consequence of central sensitization can be prevented by blocking sensory input to the CNS during surgery and the immediate post-operative period.

Condition Intervention
Breast Cancer Procedure: Paravertebral block Procedure: Sham injections

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: A Prospective, Single-blinded, Randomized, Trial Evaluating the Use of Paravertebral Block to Decrease Chronic Post Breast Surgery Pain.
