I fell down 4 steps at work (Scott AFB), went to ER, then medevac across river to trauma center and neuro specialist (head trauma) to observe bleeding/swelling of my brain. I am a GS employee. I filled out and sent the initial forms. My doctor had my home for 3 weeks and now I am back to work for 1/2 days. I have not heard anything from workmen's comp and left numerous messages to Chicago (case worker). For some reason the case has been closed already and I need surgery on my knee due to a cartilage tear. I can't get approval because of this. I am so frustrated, what should I do?
