A. When you visit a medical professional, your expectations are to be treated appropriately, to receive competent medical attention and care. However, medical professionals are also human, and mistakes occur. Medical malpractice involves damage or harm to a patient caused by a negligent act or omission caused by a medical service provider. It frequently involves error in diagnosis, error in treatment, or mismanagement of illness. If an injury occurs as a result of these negligent acts or omissions, there is cause for legal compensation.
