I fell in front of Navy Federal Credit Union because the step up was too high and I hit my forehead on the pavement.Im not sure of what to do.

In order to hold a premises owner liable for injuries on their property, you have the burden to prove that they were negligent. For example you must prove that the owner had a dangerous condition that caused the trip and fall. What was the negligence on the part of the property owner that caused you to fall? Do you have pictures of the accident site where you fell?
