Also listening. Glad you got your vaccine. That probably is why you were feeling excessively tired. But, I recall talking to my doc about the shockingly low iron that showed up in some bloodwork:

Doctor: "So you really haven't had any symptoms? Haven't you felt tired?"

Me: "*pause* Well, sure, but there are SO MANY reasons to be tired."

How is exhaustion a symptom of anything in specific at the moment??

I guess you've started and probably finished this treatment by now. Sending positive thoughts and hoping the hearing aids are awesome.
