How long do I have to file a law suit after the injury

In Pennsylvania, the statute of limitaions for a medical negligence claim is 2 years after the date of the alleged negligence, with certain exceptions. For a minor, the statute is 2 years after the minor reaches tha age of majority, which is the minor's 20th birthday. Further, the statute of limitations may be extended in certain  circumstances to the date precisely 2 years after the date  when  a reasonable person should have first suspected the  negligence of a  health care provider was causing his or her injuries or conditions. Additionally, there are special rules which apply to surgical and medical instruments left in the body. The foregoing is not an exhaustive analysis, and it is best to consullt with an attorney if you believe you have a claim, even though it may appear that the statute of limitations has expired.
