Hi all, Hoping for some advice on multiple back issues diagnosed while I was still on active duty. I hurt my back in a helo crash and was diagnosed over a 5 year period with DDD, bulging disks, spondylosis, spinal stenosis, and spondylolisthesis. It's all in my medical records and I had many documented visits to docs, MRI's, X-rays etc that explain it all. My last 2 years was nothing but trips to the hospital. I submitted and received 10% each for the DDD and bulging disks last year. I never submitted for anything else but have been told I could/should. Any issues with "pyramiding" or any other reasons the additional 3 conditions wouldn't be accepted? My back is getting a lot worse lately...so many questions to ask...thanks for any response.
