I find that Claimant, Jimmie ("Pat") Davidson was born March 11, 1955, and has an $11^{\text {th }}$ grade education. He does not have a GED, nor any other vocational training or further education. Claimant has not served in the military; Claimant testified that he tried to enlist in the Navy, but he was rejected. Claimant has been married for 31 years, and Claimant and his wife have three children.
Claimant's work history includes hauling hay, trimming trees, building pole barns, working as a handyman, working an assembly line, fork lift operator, and loading and delivering lumber. From 1982 to 1990, Claimant drove a concrete mixer.
Beginning in 1990, Claimant worked for Mihalevich Concrete Construction, Employer herein. Claimant's job title was "lead man". As lead man, Claimant was responsible for the crew's tools and equipment, and was responsible for setting up the concrete jobs. Claimant worked right along side the other crewmembers, shoveling concrete, using a jackhammer, bull float and finishing tools, and tearing out old driveways and floors.
As stipulated, I find that Claimant sustained work-related accidents with Employer and October 12, 2001, and on June 24, 2003, both accidents causing injury to Claimant's back. Prior to October 12, 2001, Claimant had experienced hearing problems, including problems interpreting speech when background noise is present. Claimant also testified that he experiences constant ringing in his ears. Claimant has never sought any diagnostic testing, care or treatment for the hearing problems. Claimant also testified regarding a loss of central vision in his left eye. There are no medical records regarding this problem prior to October 12, 2001. In the Fall of 2002, Claimant was referred by his family doctor to eye specialists in Columbia. Two laser treatments were performed which were unsuccessful. Claimant was then referred to Dr. Dean Hainsworth at University of Missouri, who performed surgery on Claimant's left eye on December 12, 2002. On a follow-up visit on February 24, 2003, Claimant was noted to have 20/30 vision in his left eye. This decreased to 20/50 on the August 4, 2003; visit, and to 20/60 on the February 4, 2004, visit. On the latter visit, Dr. Hainsworth noted that Claimant felt his left-eye visit had decreased, and has times where "he can't see anything at all".
In addition to the alleged hearing and vision problems, Claimant had back problems prior to October 12, 2001. In 1974, Claimant slipped while climbing on a machine and had one doctor visit. In 1991, Claimant had back pain while pouring a floor, and missed one or two days of work. In April 1995, Claimant twisted his back and had one or two doctors' visits. In August 1998, Claimant was seen at the Emergency Room for pain in the left lumbar area after hammering in a bent-over position; Claimant's pain got so bad he could not get up off the ground and had to be picked up into a vehicle and brought to the E.R. Claimant gave a history of a similar episode happening once before. In December 2000, Claimant was seen by his family doctor for back pain from a fall a week earlier, with some radiation of pain down his right leg. By December 26, 2000, Claimant was doing well and was released to full duty by Dr. Sparks. There is no record of back complaints between December 26, 2000, and October 12, 2001.
October 12, 2001 accident. On October 12, 2001, Claimant was working for Employer getting ready to pour curbs and gutters. He was bending over, nailing the forms with a hammer. While swinging the hammer, Claimant felt immediate pain in his back and both legs. Claimant "couldn't straighten out". The parties stipulated that Claimant sustained an accident arising out of and in the course of his employment with Mihalevich Concrete Construction on October 12, 2001. The following day, Claimant went to see a chiropractor, and on October 15, 2001, Claimant saw Dr. Sparks. An MRI done on 10/18/01 showed central disc herniations at L3-4, L405 and L5-S1, none of which were causing foraminal stenosis or canal stenosis. On 10/25/01, a lumbar epidural steroid injection was done for back and left leg pain. On 10/30/01, Dr. Sparks noted that "This gentleman had as much back pain as I have ever seen any one person have." Nevertheless, by 11/6/01, Dr. Sparks noted that Claimant was "doing well" and Dr. Sparks returned Claimant to full duty. On January 11, 2002, Claimant had CT-guided right sacroiliac joint injection. On 1/21/02, Dr. Sparks noted that Claimant "feels fine". On 2/4/02, Claimant returned to Dr. Sparks reporting no troubles and no pain. Claimant was to continue working at full duty. Claimant did not see a physician for his back between 2/4/02 and 6/24/03.
June 24, 2003 accident. On June 23, 2003, Employee slipped while getting out of Employer's truck. He fell, and his lower back started hurting. Claimant
