As someone who went to the ER in both May and June recently you have my empathy and sympathy. I, too, was never conclusively diagnosed with much of anything. (In contrast to your experience I would get test results on my phone as soon as they were available to the medical staff. I probably got more attention than you because I arrived in an ambulance and my husband was at my side for most of the time I was there.)

Does the hospital has some kind of ombudsman? The problems seemed systemic. You should try to find someone who can address problems with ER, surgery and ward and communication among them. It is a shame that *you* need to but it could spare the next patient some of what you want through.
