Immediately seek medical attention. The sooner you get a medical report, the better your chances of successfully filing a lawsuit. Have someone find witnesses of the slip and obtain their information. Their testimony will prove valuable to your case. You or someone on your behalf should take photos of the accident scene before it is changed; the more evidence, the better. If you are at a store or other commercial location, you should request that the store manager completes an accident/incident report containing your version of what happened. Obtain a copy of that report, or we will on your behalf.
