The aim of this study is to compare the incidence of chronic post cesarean pain in patients receiving quadratus laborum block and and intrathecal morphine versus control as a primary Study design: Patients will be randomly allocated to the procedure through closed envelopes and so syringes and medication will be prepared and labelled by anesthetist other than the anesthetist giving the block Patients will be randomly allocated to the procedure through closed envelopes and so syringes and medication will be prepared and labelled by anesthetist other than the anesthetist giving the block Data will be collected regarding the demographic data, gestational stage, parity and number of previous cesarean section, previous abdominal surgeries, and narcotic consumption. Postoperative pain day 1 and day2 will be followed by anesthetist who is blinded to the applied technique used. Follow up for the subsequent period of observation (2,4and 6 months) will be done by the department secretary who will contact the patients by phone to ask them if there is any "concern" after the operation. If the patient refers to a pain at the surgical site that has been lasting for the past three months a call will be conducted by the anesthetist and a referral schedule will be appointed to the pain clinic consultant for further evaluation
