Based on a comprehensive review of the evidence, including Claimant's testimony, the expert medical opinions and deposition, the medical treatment records, the other records, and the testimony of Employer's witness, as well as my personal observations of Claimant and the other witness at hearing, I find:
1) Claimant is a 36-year-old, clamp truck/forklift operator, who worked for Penske Truck Leasing (Employer) for a little over four years, from May 2008 until August 2012. After he was terminated in August 2012, he applied for and received unemployment benefits for a period of time. Subsequently, he worked for a couple of other employers, until earlier this year, when he became employed by Alpla Plastic Company (through St. Louis Staffing) as a clamp truck/forklift driver. He currently is working for Alpla (through St. Louis Staffing) full time, 35-40 hours per week.
2) Claimant testified that he is pursuing a Claim here for neck and back complaints. He testified that his job as a clamp truck/forklift driver for Employer required him to sit, twisted to the right, looking over his right shoulder with his left hand on the steering wheel to drive. He estimated that he spent 85 % of each workday for Employer in this position driving the clamp truck/forklift. He testified that he worked 12-hour days, 7 days a week for the first $11 / 2$ years he was employed by Employer, and, then, he worked 8-12 hours per day for 5-6 days a week for the balance of his time there. He said that he was primarily on the forklift driving, but he would have to occasionally pick up items as well by hand, such as microwaves or cook tops. He estimated that the lifting component was approximately 15 % of his time working for Employer.
3) Claimant testified that sitting and driving while twisted to the right and looking back over his shoulder was uncomfortable within the first year he was doing it. He said that the problems got worse as time went on and he continued performing this activity. He testified that he told his supervisor, Cory, about his problems in September 2010, and, then, later on he told a team leader, Matt Harris, about the neck and back problems he was having as well. He said that he has never received any injections, physical therapy or other medical treatment from Employer for his complaints.
4) Claimant testified that the problems became worse in 2011, so he signed up for FMLA. His Medical Certification for FMLA (Exhibit 7) dated June 29, 2011 from Dr. Misir, indicates that as a result of chronic sinus pain and infection and chronic back pain, Claimant will need to miss work approximately four times a month for one to two days per treatment between June 29, 2011 and December 29, 2011.
5) Medical treatment records from Dr. Naresh Misir at BJC North County Physicians (Exhibit 1) document an initial complaint of back pain by his kidneys, and chest and rib pain on July 22, 2009. However the records also reveal treatment in 2009 for urolithiasis (stones) that could account for the back/flank pain. Beginning on March 9, 2012, Claimant complained of moderate-to-severe right neck pain with radiation to the right arm that began one year prior to the visit. In follow-up visits in August
2012, Claimant continued to complain of severe neck pain aggravated by twisting, with radiation into the bilateral upper arms, and he was diagnosed with worsening cervicalgia. A cervical MRI taken on August 15, 2012 showed a minor broad-based disc bulge at C4-5 without foraminal encroachment or nerve root compression. By August 27, 2012, Claimant was still reporting worsening neck pain and radiation into both arms with weakness, pain and tingling.
