I am not licensed to practice law in Ohio.
I am not sure of when the procedure took place that scarred you.
However everystate has a statute of limitations ofr such claims.
Consult with a Personl Injury attorney in Ohio. They usually give free consultations.
The statute of limitations to file a medical malpractice complaint is one year. I believe it will be difficult if not impossible to get an attorney to take this case.
No, if this just happened this last May, it's not too late to sue, but I would not get your hopes up - - especially this late in the game. The Ohio General Assembly has made it very difficult to sue doctors in the State of Ohio. The Ohio Supreme Court has not made things any easier. Finding a lawyer for a medical malpractice case in Ohio is very difficult for these reasons alone.
Of course, every case is different and you have provided very limited facts. While it's possible you may have a claim, I would have to say it's not likely. I always encourage speaking to a lawyer in person. Perhaps someone will have a different take than me.
