EE initially injured his lower back on 10/7/13 by placing a pallet on a scissor-lift. The EE was taken to the ER and was released without restrictions. On 10/14/13, EE was filling 50# paper bags when he felt the pain in his back again. The EE returned to the ER and was given a release with restrictions along with medication. WC is questioning the validity of the EE claim.
