I have been suffering from Lower Back Pain for last 4 months. When sitting on chair I feel the pain on my buttocks as well. Some times pain radiates to left leg as well. My pain gets worse when I go to bed. I feel a terrible pain at my back and spine when I try to get up from Bed. I also feel pain when I try to lift any object or when I try to bend myself let's say buckling the shoe or wearing the cloth. I also feel pain when I sit on the floor.
