I want to know if I can file suit

It sounds like you are a long haul driver. You could potentially have a workers compensation claim if the lung condition was caused by an injury or accident arising out of your employment. If you work for a company in this State or have contracted with a company in this state, then North Carolina would be the state in which to file a workers comp claim. As for a medical malpractice lawsuit, that suit would likely have to be filed in North Dakota either by an attorney who practices there or a NC attorney who is granted admission in North Dakota for purposes of this case. This is known as pro hac vice admission. I am licensed in North Carolina, but have handled malpractice cases in other states on a pro hac vice basis. In any event, you should have your case evaluated by an experienced attorney to make sure all of your rights are protected. Let me know if we can help.
