The mean value of BMI was within normal range in both groups. The pain score recorded highest number of cases in Diclofenac Sodium and ketorolac group at score 02 within 30 minutes after surgery while the pain score significantly dropped in ketorolac group in 60 minutes to score 00 while it persisted highest in score 02 among patients given Diclofenac Sodium.
