Iliohypogastric and Ilioinguinal Nerve Block for Acute and Chronic Pain Relief After Cesarean Section.

Each patient will receive spinal anesthesia plus bilateral ultrasound-guided IL/IH nerve block. The abdomen will be scanned through anterior superior iliac spine (ASIS)-umbilicus line. Ilioinguinal nerve can be visualized between the internal oblique and transverse or external oblique muscles and within 1 to 3 cm from the ASIS. The iliohypogastric nerve lies immediately adjacent. After negative aspiration (to exclude intravascular injection), 10 mL of 0.25% bupivacaine will be injected. The same technique will be performed on the other side

Each patient will receive spinal anesthesia alone with no block.
