Right crank arm feels uncomfortable
Well, the thing to do first is to determine if the crank arm is bent (or loose/poorly fitted to the shaft).  

Prop the bike up and "pedal" it backwards with your hand (from the right side).  Observe whether the shaft of the pedal maintains the same horizontal alignment all the way around.  If the crank arm is bent then generally the pedal shaft will be "pointing upward" at the top of the crank cycle and "pointing down" at the bottom of the crank cycle, and you can usually both see this and sense it with your hand.

(Note that a bent pedal shaft can produce the same symptom, though.  But if the pedal shaft is bent it will be obvious if you unscrew the pedal -- the shaft will "wag" around as you unscrew it.  And either way you'll need to replace some components.)

It should be noted that, on bikes with 3 front sprockets, the right pedal sticks out from the frame slightly more than the left pedal, making your ankle slightly more apt to bump the right crank arm than the left.  But the difference is slight -- maybe 4mm.
