My goodness. You need to call and get an appointment with the medical oncologist and/or the breast surgeon. In California were had regular follow-ups. If your PA did not hear you, do not give up. You hurt and are having side effects that i never had after my surgeries. Have you had regular follow-ups? Fatigue to some degree may happen, dreams and night terrors probably sometimes. Are you on medications still? Be good to yourself and let the medical team get you some answers.
Someone else will post with experience on this. I just want you to know i hear you.
