They dont support you financially, you have not to tell them, just go away with a good trained doctor(dont do more than 6 cm per segment) knowing that complications can happen but if you surgeon knows what he/she is doing he/she will resolve it well without extra cost, in some cases. If you feel better telling them do it fast, they maybe get upset and tell you are crazy because most of the people are ignorant about this procedure, try to explain this surgery and if they understand well if not ,too. Some surgeons wont allow you to do this surgery at least one of your family member knows about it, but it is just in some cases, money is their main concern.
