I am a service connected medically discharged USMC vet discharged in 95. In 2008 started having back issues L5s1. Have had 8 surgeries and a nuero stimulator implant. I had several back injuries while on active duty. I have recently had a hearing from the appeal process with SSID, waiting on the ruling. What is my best cause of action with the VA for an increase in disability- service connection? I have been denied in the past. But didn't have anywhere near the medical evidence I have now. Any help or comments would be appreciated!!
