The Claimant was a delivery man in his position for approximately eight months at the time of the alleged injury. The Claimant alleged in his initial C-3.0 that he suffered back pain, but was not sure how it happened. He alleged that he woke up the next morning and could barely move. He assumed it must have been because of his job duties. He told his doctor about two months later that the pain began five months earlier and that there was no inciting incident. However, as the Claimant began to treat with the same doctors, he eventually stated that an acute accident occurred, that he tripped while loading boxes, fell, and injured his lumbar spine. The employer denied the claim, as the Claimant failed to provide notice of the accident until over two months after the alleged accident. Further, despite denying prior treatment to the lumbar spine, the Claimant had a history of sciatica.
