You need a lawyer I think. Why would you talk settlement now? You're going to see a doctor...see what he says.What is the name of your state (only U.S. law)?
I don't want to involve a lawyer and don't want a large settlement. I just want the gas station to cover my medical expenses and time off of work to seek treatment. Where should I start? What options do I have?
You're not going to get rich but a lawyer will insure all the bases are covered. Plus, they just don't say : here's a pile of money for you. Your delay in seeking medical treatment is an issue.
