do I have a valid lawsuit if i was seen in an er but they did not address the issue i went in for? Then had complications?

You may have a viable malpractice case, failure to timely diagnose and treat an acute appendicitis is often the basis of a lawsuit. The question will be whether the delay in harm resulted in permanent damage. If it did not, you may have a hard time finding an attorney to take you case because it may not be financially viable.  If you want to investigate a malpractice case, you should contact a local medical malpractice attorney (one in your state).  They take these cases on a contingency basis which means you only have to pay if you succeed.  Additionally, initial consultations are usually free. You can use the "Find a Lawyer" service through this website to research medical malpractice attorneys.  Then, visit each attorney's website and look for a firm that has a record of successful verdicts,  ideally with experience in cases that involve your medical issue. If you are unable to find a lawyer who meets these qualifications within your state, sometimes you may contact an out of state lawyer who can refer you to a qualified attorney in your state while providing support related to the issues of medicine. Below are some articles you may find helpful.  They are written for a New Jersey audience (where I practice) but the ideas discussed in these articles usually apply in most other jurisdictions as well.

Since I am a lawyer, I need to advise you of the following when I communicate with you: Please note that by attempting to answer your question, I am not acting as your attorney. I will do nothing further to protect or preserve your interests in the absence of any additional discussion with you about this matter. John Ratkowitz, Esq.
