Causation 101

“Edes asserts there is sufficient lay evidence of causation and directs us to testimony by himself and a co-worker that he developed symptoms immediately after the accident that he did not have before the accident. But evidence of an event followed closely by manifestation of or treatment for conditions which did not appear before the event raises only suspicion that the event at issue caused the conditions and is not legally sufficient to support a finding of legal causation.” Edes v. Arriaga, No. 05-17-01278-CV (May 24, 2019) (mem. op.) (applying Guevara v. Ferrer, 247 S.W.2d 662, 668 (Tex. 2007) (emphasis added)).
