I have septo optic dysphasia and a low pituitary and thyroid i want to get a tatoo but i'm worried if i could go into adrenal shock is that possible ?

Hypopituitarism: I did see that you are on Hydrocortisone or Prednisone which would be used if you are cortisol deficient from your pituitary condition. Even if you were cortisol deficient i don't think the stress of getting a tatoo would case adrenal crisis in someone withno history of cortisol deficiency. Just to be safe i would recommend that you ask your md when you adrenal function was last tested.
