I went back to try to talk to the doc on a separate day. I called, spoke to several people and was given the runaround. They gave me his direct number, but he didn't bother to answer. I actually went in to try to set something up and was treated even worse, if that was possible. I was left standing there as staff just ignored me. I got fed up, left, and went to Hospital Ajijic.
For the happy ending: Dr. Rodriguez at Ajijic Hospital knew immediately what was happening...from the blood results done by HSA! He arranged an ambulance, a renal specialist, and set things up at Hospital San Jose Villareal in Guad for emergency dialysis. If I had trusted HSA, hubby probably would not be here today. Yeah, it's safe to say Hell will freeze over before I ever cross that threshhold again.
BTW, the hospital in Guad was probably one of the best I've ever experienced. Quality care and rooms that were nicer than hotel suites. They really took the patient and his/her family's comfort into account when it was designed.
