You can bring a case if the statements are false (based on your info they clearly are) and can be taken as a statement of fact and not a joke or opinion. In some jurisdictions, such as Florida, a plaintiff in a libel or slander case has to prove actual damages (i.e. loss of employment, inability to become employed). Your facts suggest that you have openly not suffered any measurable damages.
However, I suggest contacting an attorney to discuss the possibility of an action. You may have suffered damages that you do not realize are recoverable.
This answer is intended to be used for general purposes only; it does not create an attorney-client relationship.
If you are merely trying to "prove a point" for a small amount of court costs and no attorneys fees, be my guest. But honestly, you will probably look ridiculous in the process and lose more respect with the people who you have fallen out of favor with.
Additionally, to win a defamation claim in Ohio you need to show damages beyond just hurt feelings. If you lose a workers comp case because of this, that might be some damages, but it doesn't really seem like you are talking about much money here. Move on.
