The goal of this clinical trial is to evaluate the efficacy of photobiomodulation of the pelvic floor muscles in female Veterans with chronic pelvic pain. The main questions it aims to answer are: * Is there a difference in reduction in overall pelvic pain between women who undergo photobiomodulation compared to women who received pelvic floor physical therapy? * Is there a difference in compliance with therapy between the two groups? Participants will be randomized to treatment with either 9 treatments of photobiomodulation (two treatments per week) or 8 weeks of pelvic floor physical therapy (one treatment a week). Researchers will compare both groups to see if there is a difference in overall pelvic pain reduction.
