If you were injured on a training exercise for the Army National Guard, you need to consult with a worker's compensation attorney about your injury and the resulting medical expenses and their payment.I would also get a copy of your unit medical insurance policy and contact the carrier to see what the problem is for getting your medical bills paid. You might also consult with an attorney that practices personal injury and insurance law about your situation and whether or not you have a basis for bringing a lawsuit against your health insurance company and your resulting medical bills.
