The Board has denied the veteran's claims for increased ratings for his post-neck injury headaches and chronic cervical strain, finding that the evidence does not support a higher rating than what was already assigned.

The Board has remanded the cases due to incomplete development and unsuccessful attempts to contact the Veteran.

The Board has determined that additional development is needed for the Veteran's claims, including obtaining VA examinations and considering his symptoms since last evaluated in March 2015.

The Veteran's right ankle strain is currently rated at 10 percent, which reflects moderate limitation of motion. The Board finds no evidence of marked limitation of motion.,For the period prior to July 26, 2016, the Veteran’s DJD of the right knee was characterized by pain and some limitation of motion; however, there is no indication of ankylosis or severe symptoms warranting a higher rating. Since July 26, 2016, the Veteran's right foot pes planus and plantar fasciitis with callus on the great toe have resulted in moderate to severe unilateral symptoms.,Prior to July 31, 2013, the Veteran did not meet the criteria for a higher rating due to cervical strain. Since then, his disability has not met the criteria for favorable ankylosis or severe recurrent subluxation/lateral instability warranting a higher rating.,For the period prior to July 26, 2016, the Veteran's major depressive disorder did not result in occupational and social impairment with reduced reliability and productivity. Since then, his condition has resulted in such impairment but not to the extent that it would meet the criteria for greater disability.

The Veteran's degenerative disc disease of the spine is now rated at 40 percent, effective February 5, 2016. This rating reflects significant limitation in forward flexion.
