Exostosis is a medical condition characterized by the abnormal growth of bone tissue on the surface of a bone. This growth can occur in various locations, including the skull, spine, and limbs. Exostoses can be caused by factors such as repetitive stress, injury, or certain genetic conditions. While many exostoses are benign and do not cause symptoms, some can lead to discomfort or complications, depending on their size and location. Treatment options may include monitoring, pain management, or surgical removal if necessary. Regular check-ups with a healthcare provider can help manage the condition effectively.
