I've had 2 back surgeries in the last 30 days and a 3rd scheduled for May 11th. I start short term disability on May 11th as well. Can I apply for TDIU at that point? I have DDD and had to have a disc removed and 3 weeks later, the vertebra above the disc collapsed and pinched the nerves that control my legs. I now just found out that I'm leaking spinal fluid and it needs repaired. This is the May 11th surgery. I'm only rated at 50%, however, I applied for an increase after my first surgery. The VA doesn't know about the other 2 surgeries yet. Basically, I walk with more of a shuffle and have to deal with my legs giving out on me from time to time. It's extremely painful. Every day. I'm going through bouts of depression(not SC'd). Sometimes I sit in my chair and cry because I can't get rid of the pain or how I can't get off the floor easily. The reason I think I should apply for TDIU is because I have to have the ability to lift 100lbs as part of my job description. There is no way I can do this now or in the future. I can't even sit for more than 30 minutes without pain radiating down my legs. My feet are numb all the time. etc,,,etc,,,
