My husband was hurt at work while attempting to move a 4500 lb crate with a floor jack. The crate was on a truck and they were attempting to move it out far enough to get a fork lift under the side. When it let loose it pinned him between the handle of the floor jack and a cart that caught him in the back of his thighs. The floor jack handle hit at hip-bone level and bent him back slightly. He now has a severe sharp pain in his left lower back and can not feel his left leg. The doctor is treating him for an acute lumbar strain. He has since had one episode where his left leg went completely paralyzr=ed for a few seconds while attempting to walk up the stairs. He is scheduled for an EMG, but only after he called to WC Insurance company and complained. I am very scared that their is a more severe injury that was missed. Any suggestions on what we should do next?
