can i open my case again , it work compensation case ?

If your condition gets worse, an injured worker in California can reopen a case that was resolved by Stipulations and Award or by an Award by a Workers' Compensation Judge, with future medical open, by filing a petition to reopen with the Workers' Compensation Appeals Board within Five years from the date of the initial injury. That means that you have until March 25, 2013 to file that petition. You need to have some evidence, such as doctor's reports, that show you are worse off. However, if you settled your case by way of a Compromise and Release, giving up your right to future medical care and receiving payment in a lump sum, you have probably given up your right to reopen the case, even within five years. Examine the settlement documents you did sign carefully, to see which type of settlement you have.
