This is essential for proper healing and to prevent complications.

Long-term postoperative care often involves gradually increasing physical activity, closely monitoring the surgery area for signs of infection, and following specific instructions regarding wound care and pain management. It's important to follow the healthcare provider's recommendations regarding the use of prescribed pain medication rather than relying solely on over-the-counter options, as post-surgical pain management is tailored to the individual's needs.
