"I don't feel this was professional"

I’ve struggled with palpitations, lightheaded ness, dizziness resulting in losing feelings in my limbs and either falling over or feeling of blacking out. I also get chest pains occasionally to accompany this. I received a 48hour tape and they found what I was talking about as well as short gaps between beats/skipped beat. However because I’ve had it so long they are happy with the results, and suggested is the other symptoms causing the heart problem and because I’m young and female it’s seemingly normal. I could accept all of this until the staff member said to me as another nurse was present in the hallway that maybe more regular exercise would help.  I responded that I work pretty much on my feet and the staff member replied that maybe I should consider more regular shifts. I said that I work 12 hour shifts 5 days a week and the staff member's response wasthat maybe that’s too much then.

I dont feel this was professional at all.
