I am sorry to hear about your diagnosis of AML Leukemia but am very happy to hear you are in remission! Certainly that does change one's perspective on life and health. And I understand your concern that you are still recovery with regards to your immune system and going to the Emergency Room. That is a valid concern. Would your personal doctor/general practitioner examine you in their office today? That way, you can avoid other people that are ill exposing yourself to a host of things this season including the flu. Secondary infections of the flu when you can't fight them off can be deadly. Here is some information on staying well when your immune system is compromised: https://www.webmd.com/cold-and-flu/features/weakened-immune-system#1. You could go to the ER but wear a surgical mask to help protect yourself and take your own hand sanitizer. I'd inform them that you are in recent remission and perhaps they have an area that they have for people in your situation to reduce germs. Or they could take you straight back.
You likely are getting over bronchitis and need antibiotics. Your doctor is your best place to visit over the ER in my opinion and calling ahead could help you avoid the waiting room altogether. Let us know how you are doing.
Sorry for the wording there, my computer twisted my words around.
Sorry to hear about the fever. I am sure any time that you've had a serious illness such as you have had, this makes you nervous. Please let us know how the ER visit goes and we wish you the best.
