I Went For Disability From The VA And They Gave

I went for disability from the VA and they gave me 40% for the left and right lower extremity. Moderately severe. A year later they sent me to an outside doctor to get re-evaluated and want to give me 20% saying it's moderately incomplete. My legs don't feel better. They feel worse. Also can peripheral neuropathy contribute to loss of toes. I have diabetes type 2.
