No. If you're hurt at work, your medical expenses are the responsibility of your employer or their insurance company. That's a lifetime benefit, so long as there is medical evidence, as ratified by the Workers' Compensation Commission, that you're experiencing a health condition that's related to a workers' compensation event. Even if that event is remote, you're entitled to have that insurance company or that employer pay for your medical treatment, in theory, for the rest of your life.
