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 simplest and the most common cause of forehead lumps is simply a reaction to the fact that you have hit your forehead on the hard surface at some point. When this happens, a lump may form and be quite painful to the touch. This is not a cause for concern, and the lump should go away on its own in a few days.
