I filed on my own for back, hip and arthritis, in 97, its in reconsideration since june, I started working, and tore my rotator cup

I dont remember appealing, but went down to file for the rotator cup injury thursday, and found out its in the reconsideration phase. I had to leave work today for pain, told I need surgery, I'm thinking I need to get a lawyer involved. I injured it (not at work) in Janurary when I tripped when I lost feeling in my leg. It took me until last month to find a dr. get an mri, and get diagnosed. My insurance covers little of the cost, and I cant keep working through the pain, it just gets worse daily.
