The ER note saying "possible herniated disc after lifting/fall" helps him; the insurance company will read that same note looking for anything vague, delayed, or missing so it can say this was a preexisting back problem instead of a new Warren injury.

1. Get the first medical records locked down. Ask for the ER chart, discharge papers, imaging orders, and ambulance records if one was called. What matters most is whether the record ties the pain to a specific date, time, and mechanism at the storage facility. If the chart just says "back pain" and not "hurt while lifting or slipping at a self-storage site," insurers use that gap against you.

2. Preserve scene evidence immediately. Storage facilities often overwrite video fast, especially near year-end when staffing changes and policy renewals happen. Send a written demand to preserve surveillance footage, incident reports, gate-entry logs, maintenance records, snow/ice removal logs, and employee notes. In Warren, photos of the exact unit, hallway, loading area, cart, puddle, ice patch, or broken surface can matter more than later arguments.

3. Document the back condition before and after. If he had prior disc issues, that does not kill the claim. You need records showing the difference: older treatment notes versus the new symptoms, new MRI findings, work restrictions, numbness, weakness, or radicular pain after this event. Michigan law allows recovery when an incident aggravates an existing condition.

4. Collect witness and timing proof. Get names, phone numbers, and short written statements from anyone who saw the fall, heard him complain right away, or helped him leave. Keep receipts, timestamped photos, and phone location data showing he was at the Warren facility.

5. Avoid the mistakes that wreck value in the first 48 hours. Do not give a recorded statement with guesses. Do not post on Facebook, Instagram, or TikTok. A single photo of him driving, lifting groceries, or standing at a family event becomes "proof" he is fine.

6. Watch Michigan's deadline. For a negligence claim, the general filing deadline is usually 3 years in Michigan, but waiting is how evidence disappears. If there is any dispute over emergency response or reports, request records early from the Warren Police Department or EMS provider while the paper trail is still easy to trace.
