My x-rays of my right leg showed the hip is almost bone to bone and thinning of bones in ankle, Also I have osteoaethritis in hip,knee and ankle. what can I do on my own to help relieve pain and get more movement?

Pain when I sit for awhile and try to get up. Hard time bending to pickup something and limp when walking. Trouble sleeping at night (every two hours I wake up to adjust leg or because of pain or cramping in ankle). The pain is sometimes sharp and stabbing in upper thigh area near joint of hip,
