In 2002 i applied for disability claim with VA and it was 100% denied, then i appealed at the time and several items were accepted and i was given a rating in 2003. Many years have passed by and im re visiting my claim due to allot more pain. What i'm wondering is if i can appeal again for a higher rating along with hopefully getting other service connected issues approved this time? I feel it was done quick and minimal just to get me to go away since they initially denied 4 different surgeries while active duty. I also have my first scheduled Dr appointment to get assigned a primary care dr at VA in 2 weeks. Wondering if i should cancel that appointment till im done with an appeal? Kind of worried i may be shooting myself in the foot seeing their dr before a possible appeal. Any thoughts would be great.
