Is "ick" related to "ichor"?

I believe that the word "ick," and by extension "icky," is related to the word "ichor," or to a mispronounciation of "ichor" (the pronunciation of "ichor" is disputed).

Ichor is certainly icky.

: a thin watery or blood-tinged discharge

I found nothing on the web that etymologically links the two. Thoughts?
