Yeah, I think I'll have to take the bike into the shop and let them have a
look at the "fit" for me.

Catnipped;

Do you get a tingling feeling in your thigh before the sleep feeling in your
foot? I'm wondering if its a circulation problem that may be left over from
the pneumonia.  Are you still drinking plenty of fluids?

I'm going to second Helen's suggestion: check the position of the cleat
(fore/aft, left/right, and rotation). This seems to be the culprit
especially on relatively small pedal/cleat combos (SPDs, for example).

As you've changed pedals/shoes, you've changed your bike, and this
change trickles out everywhere else. Clipless pedals are generally
thinner than platform pedals, so you might have too high a saddle. If
you have tinkered with it, check to make sure it's not slightly out of
rotation (been there; done that).

A general fit check never hurts as you get more involved in the sport.
Check with the bike shop to do an assessment (probably a "professional
fit" is overkill). Or, check with your local bike club--they often have
knowledgeable people who might help. Plus, you might find some cool
people to ride with (been there; still do that).

Cheers,
Charles
