Jimmie Alston ("Claimant") was born on September 4, 1967. As stipulated, Claimant was injured on March 17, 2008 while in the course and scope of his employment with Dish Network ("Employer"), a satellite television provider. Claimant began working for Employer in 2007. He worked four days a week; he testified that it was not unusual to work fifteen hours or more in a day. On March 17, 2008, Claimant was working as a "Field Service Specialist II" (satellite dish system installer) for Dish Network and was at a customer's residence in Higbee, Missouri during a rain storm. As Claimant was carrying a 16' ladder (called a "Little Giant") back to the company van he slipped in mud and fell backwards onto a rock/gravel flowerbed, landing on his back, with immediate pain in his low back. Claimant notified his supervisor, Robert Wilson, of the injury that same day, who asked him to first go to see a chiropractor for his pain. Claimant went to Pressley Chiropractic for three visits for treatment, but with no improvement of his low back pain. He filled out a written report of injury for Employer, and the Employer/Insurer authorized treatment at Urgent Care at University Hospital, where he received treatment by Dr. Tran on March 24, 2008, for low back pain and pain down his left leg. Claimant was taken off work, and was treated conservatively and then referred to the University's orthopedic clinic. Claimant was then seen by Dr. Joel Jeffries on May 7, 2008, who ordered an MRI. The MRI of May 14, 2008 showed a large central extruded disc fragment at S1. Dr. Jeffries told Claimant he had a herniated or "blown disc" and referred him to Dr. Theodore Choma, an orthopedic surgeon at University Hospital, who recommended surgery on the disc. The surgery was authorized and Dr. Choma performed an L5-S1 laminotomy and microdiscectomy on May 27, 2008.
After the surgery, Claimant followed up with Dr. Choma, but had a lot of fluid draining from the wound and possible infection. Dr. Choma released Claimant to light duty work on June 11, 2008. Employer had Claimant working light duty assembling satellite dishes, sitting in a plastic chair which aggravated his back pain, which he reported and was told by a company nurse to buy a "donut" for his chair. Although the surgery did improve his back pain, Claimant continued to have numbness radiating into right his buttock, and he noticed that his right calf was still weak.
Dr. Choma released Claimant back to full duty work as a dish installer as of August 4, 2008. Claimant was sent back to work on three or four "big jobs" (bigger houses, requiring more wiring work) when on August 6, 2008, he claims he sustained another work-related back injury. Claimant testified that he was working on a house in Jefferson City that had not been "pre-wired" and was carrying a 28 foot ladder weighing 85 pounds back to the van, and as he twisted to swing the ladder he felt increased pain in his low back. Claimant testified that he finished the day although his back was hurting, and later that evening he drove his daughter to college in Tulsa, Oklahoma, and stayed overnight at his parents' house in Tulsa. Claimant testified that the next morning when he woke up, he went to get coffee in the kitchen and as he
was standing at the kitchen counter he instantly felt severe pain in his low back and right leg, and that he "knew right away" that he had re-injured th
