The Board found no evidence of current disability with respect to the veteran's hands, knees or right hip. The Board denied service connection for arthritis and disc disease of the lumbar spine, and arthritis of the thoracic spine, hands, knees, and hips as there was a complete absence of competent medical evidence relating these disabilities to any incident, injury or disease of active military service.

The Veteran's post-operative right inguinal hernia has not been shown to be recurrent. The most probative evidence of record reflects that for the period on appeal the Veteran has been shown to be unable to secure or follow a substantially gainful occupation due to his service-connected disabilities.,The Veteran is already in receipt of a separate 10 percent rating under Diagnostic Code 7802 for his residual, scar post-operative right inguinal hernia. A higher rating under Diagnostic Code 7802 is not warranted.,The Veteran's combined evaluation exceeded 40 percent from March 23, 2007, and he meets the schedular requirements for entitlement to a TDIU.

The Veteran's arthritis of the thoracic spine is rated at 40 percent prior to March 11, 2019, and at 20 percent thereafter. The Board has also granted separate 20 percent ratings for RLE and LLE radiculopathy since August 3, 2018. Service connection for left leg restless leg syndrome is remanded as it is claimed as secondary to service-connected arthritis of the thoracic spine.

Service connection has been granted for arthritis of the cervical spine, thoracic spine, lumbar spine, hands, right knee, left knee, migraine headaches, and sinus condition (to include allergic rhinitis).,Prostate cancer has also been granted.

The Veteran's PTSD, along with his back and knee disabilities, has resulted in a TDIU effective March 30, 2006. The Board granted a 70 percent disability rating for PTSD effective the same date.
