settlement not final yet

[bothknees]

I am a medically retired California State Employee. I was put on permanent and stationary status over a year ago. I know I am an unusual case being that every agency involved has been great! and I have not had to seek an attorney yet?. Workers comp put both my knees from seperate injury dates onto one claim, which is now just one settlement, and I have been recieving payments from them every two weeks. My question for anyone?, is that my knees have gotten worse!. Working my new job with no problem's for 10 months now, suddenly yesterday my left knee filled up with fluid and swelled up almost as much as the first time this whole issue started 4 years ago. I see the doctor on monday, and my case a WC has not gotten final approval yet. Being that my condition is getting worse and affecting my employment options even more now, should I get a lawyer and re negotiate my claim?. Has anyone gone through this scenario before?.
