I have injured my back a few months ago. However the time that I went out of temp disability didnt occur until maybe after 20 days and I may have added injury to injury by continuing working. When I told my superisor about my injury she kept on delaying the paperwork until i finally couldnt perform my job. Four months later a negative Xray and a MRI that shows arthritis according to my W/C doctor, I am still having back problems which is now consistently in my lower and middle back and pains that go down my leg. I went from being able to walk and stand from 30 min to about past an hour and a half with PT. However my back pain occurs within 15 minutes to over an hour. My doctor kept hurrying me to go back to work despite my symptoms and has now cancelled PT and released me.
