Yes, it is possible to file a medical malpractice lawsuit in the event you are misdiagnosed or if a medical professional fails to diagnose your condition. If a medical professional fails to diagnose a serious injury or illness, the patient could indeed suffer from severe long-term consequences.
It is important to note that the Illinois medical malpractice statute of limitations is two years from the date the patient knew or should have known a misdiagnosis caused them harm. There are a few exceptions to this two-year window, so please speak to an attorney about your case as soon as possible.
