It sounds to me like you might have trapped the sciatic nerve if you are in that much pain down the one side.
Give NHS direct a call in the first instance on 0845 4647. They are very good and should help get you some pain relief.
I find sleeping on my side in the foetal position eases things when I do my back in, and keep your feet and knees together when you get out of bed as I find this the most painful bit in the morning. Regular gentle stretching helps to keep things moving.
A very good friend of mine is an osteopath. I do swear by the work they do and have helped me when conventional treatment has failed.
