"We may not reweigh the evidence that was before the Commission." Burton v. Nissan N. Am., 305 So. 3d 1163, 1169 (¶18) (Miss. Ct. App. 2020) (quoting Wright v. Turan-Foley Motors Inc., 269 So. 3d 160, 167 (¶26) (Miss. Ct. App. 2018)). "If the Commission’s order is supported by substantial evidence, this Court is bound by the Commission’s determination, even if the evidence would convince us otherwise if we were the fact-finder."
Bowdry failed to provide any admissible evidence of medical records or expert testimony. He testified at the hearing in front of the AJ, but his testimony was not enough to prove his neck injury was related to his work-related injury on April 21, 2017. "[I]n all but the simple and routine cases it is necessary to establish medical causation by expert testimony." Burton v. Nissan N. Am. , 305 So. 3d 1163, 1170 (¶22) (Miss. Ct. App. 2020) (finding appellant with pre-existing back pain had to prove by medical evidence or expert testimony that his disability had a causal connection to his employment). Bowdry had a history of three prior work-related injuries to his neck, so he had to provide an expert witness or medical evidence.
