Possible Side Effects

I read the side effects
Suggesting what I might feel,
Or not.
That slight sense of dizziness,
Pehaps a coincidence,
Or not.
In which case I might be experiencing
A side effect
“This medication could increase a state of anxiety”,
Well, how would one know
Already anxious from the state of
Possible dizziness?
Certainly, the “loose stool” is real
Not conjured from a anxious state,
Either real or not,
Yet, I have heard anxiety could promote
A heart attack,
Certainly a real event.
I might be sensing a rash coming on,
My skin feels warm, rather clammy.
Is this what is meant by “flush”?
Well, why wouldn’t my heartbeat increase?
Certainly less common, but not if
Anticipating a rash that may or may not
Be presenting itself.
The Z-pac I took for what may or may not have been bronchitis
Expired two years ago.
Maybe that means something foreboding,
Or not.
