You can't sue your employer (i.e. get a settlement) if you have been accepting Worker's Comp. Worker's Comp is an alternative to a lawsuit--you can get Worker's Comp, or you can sue in many cases, but you don't get to do both. If there was an non-employer or co-worker who contributed to or caused your injury (e.g. an equipment manufacturer, if equipment was defective) you may be able to sue that person or business.
