Either way I'm screwed.

So a month ago I fell down the stairs and hurt my back. And then Sunday, when I thought that finally my back was better and all was right in my life. I end up bending over to put a bag in the trash can and get this very sharp agonizing pain in my lower back that shot down my left leg. It caused me to lose my footing and fall to the floor where I remained for a few minutes. I couldn't move because every time I tried it would hurt so bad that I was screaming. Matt, my dad and my brother gave me a blessing. After Matt got help from my brother to get me in the car and he took me to the ER. The doctor I saw suggested that I get an MRI but he said that it would be better if my actual doctor ordered it so the insurance would pay for it. The doctor at the er thinks that I have a herniated disk. So today I went to my doctor who basically told me that I have to be on "light duty" which means that I can't lift anything over 5 lbs, can't bend, twist, push or, pull anything and that while I'm on my pain medication and muscle relaxer I can't drive. And honestly with my job "light duty" doesn't exist. which means I'm pretty much worthless to them. So now I really don't know what to do. You see I could listen to my doctor and have the possibility of being fired . Or I can ignore the pain and my doctor and could end up making my back worse. Either way I'm screwed.
