HONOLULU (HawaiiNewsNow) – A pain management doctor accused of getting a patient hooked on opioids is now being sued, along with the medical group he belongs to. Phillip Nico, 67, says his longtime pain management doctor, Spencer Lau, “intentionally misdiagnosed” his back pain in 2012 to prescribe “unnecessary” amounts of oxycodone ― 180 pills per month.
