On 2/4/18 employee fell while getting on a scissor lift truck causing a contusion to EE's left hip, did not report the incident & on 2/5 EE was noticed limping by supervision & asked what happened. EE explained & was alright, on days off was not better so EE doctored on 2/9 not mentioning it was work related. 2/11 doctored again & was given restrictions making this reportable.
