A rare procedure is a process that is conducted with the aim of evaluating, assessing, or diagnosing a patient's condition or parameter. Surgical and physical therapy procedures are examples of surgical procedures (i.e., procedures that are intended to treat, heal, or restore function or structure). If you go to a hospital or an outpatient clinic, knowing what to expect before and after a medical procedure will help you plan. Both medical procedures have advantages, drawbacks, and potential side effects.
