Messed up again

So this time I really messed up. Started running 10 days after c-section. Felt good , increased my mileage each week. 8 1/2 weeks post op I decide to run a 4 mile race. Ran in a 7:16 pace. Went out fast first 2 miles under 7 minute then I faded. I cross the line and my right side seizes in pain. A lot of pain. I barely make it home. Have not run in 10 days and am getting an MRI today. I can barely walk , can't pick up my baby, am very depressed VERY depressed . Feel like I may never walk right again let alone run. Have seen 3 specialist , 1 said I should go on disability since my job is 4 floors of stairs , that at this point I can't walk. I have gotten a million different answers as to what it is and what will solve it but nothing works . Have been told it is my sciatic nerve, Pylformous syndrome (spelling totally wrong), Tight quads , hips out of alignment. Been told to stretch , don't stretch , Strengthen , don't strengthen , Ice, heat . I still want advice , you never know. It is pain near or about the sciatic area that then travels a bit down the outside of my legs. 2 doctors told me my hips are out of alignment making one leg shorter then the other. So i tend to believe the 2 of them. I dont think Iwill be running for a long time . But at this point I just want to walk. :( very depressed
