| Pain assessment | Pain will be assessed via Visual Analog Scale (VAS) at Baseline, 3, 7, 14, 21, and 42 days after surgery. A line of 10 cm will be used in which at the left end of the line will have a verbal anchor stating "No pain" and on the other end the verbal anchor of "The most intense pain that I ever felt". The subjects will place a mark on the line and the distance from the beginning of the line up to the mark will be measured and recorded. |
