Lower back pain in left side and left hip the pain and comes when bending on that side. The pain also shoots down in my left leg as well it hurts bad?

Back pain. Pain shooting down the leg is likely sciatica likely from a pinched nerve in your lower back. It would be worthwhile to see a neurologist or neurosurgeon for a further evaluation.
Sciatica. Pain in the distribution as you suggested describes the pattern of the nerve that travels in the leg called the sciatic nerve. The sciatic nerve is not the cause of the pain source, it is the result of an irritated nerve typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease requiring further evaluation by a spine specialist.
What is tender? Most likely if you have not injured you hip, the pain is from muscle and fascia that holds you together and moves you. Check your lower back, buttocks, and thigh for tender ropes of muscle, knots in the muscles, and tenderness where muscles attach or come together. These are likely to generate the pain and radiating pain. www.blatmanhealthandwellness.com get winners' guide to pain relief book/ball.
