By Michael Perry, M.D. Degenerative disc disease frequently causes lower back pain, otherwise known as lumbago. This condition is one of the most common and can arise due to a variety of factors, including sudden trauma, but the most common reason for developing degenerative disc disease is simply growing older.
Background: Bony raised bumps on the forehead are not rare and are known as osteomas. They occur due to the development of normal bone under the periosteum of the non-hair bearing forehead.They are benign overgrowths of bone that are non-mobile.arge frontal osteomas that are more than just a bump on the forehead are rare. But they present differently due to their size and their association with other symptoms such as pain. A CT scan will show that the osteoma is more aggressive as it extends deeper into the skull bone and is a truly expansile bone lesion.
The cause of otosclerosis is unknown. However, there is some evidence that it may be passed down through families. People who have otosclerosis have an abnormal sponge-like bone growing in the middle ear. This growth prevents the ear bones from vibrating in response to sound waves. Such vibrations are needed in order for you to hear. Otosclerosis is the most common cause of middle ear hearing loss in young adults. It typically begins in early to mid-adulthood. It is more common in women than in men. The condition may affect one or both ears. Risks for this condition include pregnancy and a family history of hearing loss.
