Intially, use a cold pack to bring down the swelling. After that, use a hot pack to increase cirulation to the area and promote healing. Try some therapeutic grade oils to structurally realign your spine and bring circulation to your back to help it heal. Valor oil blend applied to the bottoms of the feet will hellp with realignment. Helichrysum and Peppermint oils applied to the area where your disc slips will help your back heal.

This injury happened more than ten hours ago. Use warm moist heat only. Heat will dilate the blood vessels and speed up recovery of damaged muscles etc. Cold is only indicated at time of injury to control swelling and bleeding. This occurs because cold constricts blood vessels.
If you were diagnosed with a slipped disc than I would suggest you try spinal decompression exercises, they may be very helpful to you. Here is a video showing how to do an excellent exercise, hope it helps:
