Hi, Thanks for writing in. There is degeneration of lumbar spine disc between L 4 and L5. This is resulting in the disc herniating between the bones. The nerve roots pass through these neural foramina and you might have severe nerve root compression at that level. There is also degenerative changes at other levels as mentioned by you. The nerve pain may be controlled with restricted physical activity and pain relief medication. Please do not do heavy physical activity till you are comfortable. There are medications given for neurogenic pain and it works in most patients. You may also apply muscle relaxants and pain relief ointments. Surgery is indicated for those in severe pain that is not responding to medications for few months. Laser assisted surgery is available and it is minimally invasive with good results.
