In Cities Services Co. v. Ellison, 698 S.W.2d 387, 389 (Tex. App.--Houston 14th Dist. 1985, writ ref'd n.r.e.), the Court found a layperson could determine, in reasonable medical probability, that the plaintiff's damages arose from the defendant's negligence. This personal injury case involved an oil field worker who sustained injuries to his lungs, ribs, back, kidneys, spleen, colon, pancreas, and abdomen. Id. at 388. The plaintiff alleged that the injuries arose when he was struck in the chest and abdomen by tongs that were pulled off a section of the drilling pipe. Id. The court found the testimony of the plaintiff, his wife, and a rehabilitation counselor sufficient to establish a strong, logically traceable connection between the oil rig accident where the plaintiff was struck in the chest and abdomen and the plaintiff's scarring and multiple injuries in the area of his chest and abdomen. Id. at 389. Medical testimony was not necessary to prove that an object striking the plaintiff in the chest caused the scarring and multiple injuries to plaintiff's chest. See id.
