Military wavier ?

I want to join the Military. However, I take blood pressure medication. My blood pressure is controlled with my medication. Is it hard to get a military medical waiver for high blood pressure? I’m also lactose intolerant.. although, I don’t have lactose intolerance on my medical record. My blood pressure cause isn’t known yet. I’m healthy weight! I don’t want to give up hope! However, does anyone know how hard it is to get a medical waiver? I’m open to any branch of service.
