Itchy Itchy

I'm covered in a rash
That's both speckled and red;
The worst time of day
Is when I'm lying in bed.
I've been to the doc,
And called on the phone.
Three visits and three calls,
I'm becoming well known.
They can't seem to figure out
Exactly why I'm itchy.
I hope they figure it out soon,
Because I'm getting quite bitchy.
