While at my last summer internship I became sick a missed several days of work before I was diagnosed. I told my bosses what I had and once I got everything under control, my condition no longer effected my work. Now I'm applying to new jobs and using my old bosses as references and am wondering if they can or likely will tell any future employer exactly what condition I have. I understand that they will probably mention that I was sick, because that was the one thing that was bad about my internship, but can they tell future employers exactly what I have?
