**5. How does an inadequate treatment affect postoperative pain?**

An inadequate treatment for postoperative pain can have a meaningful impact in a patient's recovery and his experience in his whole hospital stay. Uncontrolled pain can lead to anxiety, depression and prolonged hospital stay.

Postoperative pain is a common complication after surgery and can be caused by tissue damage, inflammation, and nerve manipulation. If not adequately controlled, pain can lead to a series of complications, like a prolonged hospital stay, greater risk of infection, and respiratory complications [18]. Pain can also affect quality of life, which can lead to a negative impact in patient's recuperation [19].
