When I sue a company for negligence can I give my computation of how much compensation I should have?

I am confused about my case and been thinking to fire my attorney but maybe there is another way around this. I have had him for 1 year representing me in this injury case. I think he has never been in this complex type of case and has hired a co attorney to help. When the case was filed in the federal court it was filed for high 6 figure amount but that I never had a say in it was just done and I never signed for this or talked about this amount. I am very unhappy and have not spoken to my attorney about this. I was just offered an Plant Engineer position with a company in which I have many years experience in and the amount was in writing at $70,000 a year for 6 months with a raise to $75,000a year and many specialist doctors and primary doctor after this said I can never return to work I was 44 years old at time of accident. Computing 70,000/yr at 23years till retirement is $1,610,000. Since retirement now is 67 years old, I have a master degree in Mechanical Engineering now also i have medical bills that at present are about $60,000. I have been told I will have treatment for rest of my life and I have to someday have surgery on my L5/S1 in my back and that can range between $50,000 to $75,000 and up but orthopedic surgeon recommends do not do till i get older or till i cant stand it any more and have a major nerve injury to left arm no one can do anything about other then shots into my elbow area for life i have seriously a lot of pain in which for pain and suffering i figure wages and medical and future medical of $200,000 added together times 2 for pain and suffering would be the right amount as long as the court allows it and i do know that it would be up to the court to award this amount in which would be $3,620,000 total amount sued for on myself and I don't know but i was informed about loss consortium for my wife which has never been mentioned she has it very hard.
