Whether Workforce Safety and Insurance can deny continued medical benefits for a work-related injury based on alleged pre-existing conditions

1. Why am I not entitled to further Workforce Safety and Insurance (WSI) benefits for a back (and shoulder) injury I sustained while working in North Dakota for Badger Pressure Control over 10 years ago (Nov. 2014). Workforce Safety and Insurance accepted liability for the injury in 2014, however they are now refusing to cover future medical. Its bad enough they stopped paying for my pain medication, now they are refusing to pay for my medical bills. 2. Workforce Safety and Insurance stated I had “pre-existing conditions ”, I would like to know where they are coming up with that as I had no limitations or issues prior to the work related injury.
