Is there anything I can do if a hospital doesn't do anything about my illness?

Yes, go to a competent doctor. if you do not have any insurance, then you are stuck with medical care that is just concerned about getting paid and so they keep their expenses to a minimum. You want good care, someone has to pay for it. Complaining is not the answer.

This is a medical question, not a legal question. Since you have found this site on the 'net, I suggest you research medical sites as well, that may give you more information as to your condition and symptoms.

The doctors are certainly more knowledgeable than some attorney. So I would defer to them. You might do some Google research to ascertain all of the possibilities for the breast discharge. Then you might be able to ask some more intelligent questions of your physician. You might also call some other physicians to inquire of what you can do or what tests can be run to ensure you dont have breast cancer.

First, you need to determine exactly what the medical situation is so you can get treatment if necessary. If the previous doctor and emergency room missed a serious situation which leads to damages, you would have a good lawsuit.

Go to another doctor or hospital that takes your complaint seriously and performs diagnostic testing. It is unlikely there is any legal remedy for your situation unless you do have a serious medical condition and it could have/should have been caught sooner. You could speak with a medical malpractice attorney, but you will need some type of testing and diagnosis as to what condition you actually have before they could advise as to whether they would be interested in looking into a case for you.
