Bone hyperplasia is mainly caused by degenerative joint changes. The symptoms vary depending on the affected area. For example, bone hyperplasia in the cervical spine can cause symptoms such as limb pain, numbness, weakness, dizziness, and nausea when it compresses and irritates vessels and nerves. Bone hyperplasia in the joints can lead to joint pain, swelling, fluid accumulation, restricted movement, and even deformities. In the case of lumbar spine bone hyperplasia, when it stimulates the nerve roots, it can cause symptoms like back and leg pain, and numbness and weakness in the limbs. Thus, it is evident that the symptoms of bone hyperplasia differ depending on the location.
