Problems Secondary to a DVT

[Navy Vet Marine Wife]

I am rated at 60% SC for a DVT in my right leg (40%) and Raynaud's Syndrome (40%). I have applied for an increase along with adding arthritis my left knee, due to an uneven gait and was denied, and the arthritis is not SC. I have appealed this finding but have been told that an increase in the DVT and Raynaud's is almost impossible.

I have applied for my back as being secondary to my DVT because of an uneven gait. My right leg is larger than my left, and has been since my DVT in 1989, this has caused my pelvis to be tilted to the left. I believe this has led to the scoliosis that I now have and sciatica. I went to a C&P exam and the examiner noted all of my problems, and even says that I am Unemployable, but he says that my back is less than likely due to my leg. I have not received my rating from this yet, but I am wondering how I can convince my PCP that my right leg and possible Post-thrombotic syndrome has caused my back problems. 

I am not sure if anyone can give me advice but I would appreciate any advice.
