Suggest Treatment For Pain In Gluteal Region And Leg After An Injury

Hi, Can anyone help me. I am a survivor of a near fatal car accident which occurred 2 years ago. I had a grade III laceration of my spleen; my spleen is still with me. I fractured my pelvis in 5 places and have very little feeling in my left foot and lower calf. My muscles in my thigh are beginning to atrophy and my knee now locks and swells. I contiue to suffer from +1 edema which seems to be improing somewhat if stay off of it. I also had an enlarged heart and mediastinum which disappeared following CT scan. Multiple Chest x-rays were performed because they thought I tore my aortic coil which obviously I must not have. I am still having problems. Since my accident I have had an acidic type of stomach which was exactly what I felt immediatley after the accident. The pain that I still suffer in my gluteal region and my entire left leg is horrible. Sometimes I thing I am not going to be able to take anymore. I have had so maby CT scabs that I am not allowed to have anymore. How do I know that my spleen is ok and that I am not going to get worse in regards to the leg. One of the radiologist said I had a pars defect and I was able to find older x-rays predating the time of my injury which means I am told that I probably have a non-helaing or slow healing fracture. Can you help me???
