Pain from spondylosis is caused when the vertebrae shifts out of proper alignment and rub against each other. Bony growths called bone spurs may also form on the irritated vertebrae. The vertebral shifting and the excess bone growth can reduce the space through which the nerve roots travel, and the nerve roots or the spinal cord can become painfully compressed.
Symptoms vary based on the complexity of the brain, the type of tumor and its location. A tumor could cause physical problems including headaches, nausea and seizures. It can also cause behavioral changes such as confusion and impulsiveness.
Tumors are treated in different ways including medication, radiation or surgically removed.
