Chris,
I would undergo further blood tests, and wait until it
is confirmed tha your monocyte level has returned back to
normal. It is very easy to get a relapse of Mono even when
you think it is gone. Also, in case you weren't told, I
wouldn't play any serious contact sports for the next three
to six months. Mono can affect the integrity of the wall of
the spleen, and it is possible, although improbable and
unlikely, that you could further injur yourself. I don't
mean to scare you but i'm just laying down the facts.
Keep on resting,
Neil
