While you're smaller than me, unless for some reason you have extremely small arms it really should not be an issue. I'm led to believe that its you, not the bike and what you really need is to do some more stretching. Riding on a road bike is not meant to be particularly comfortable. You will get better and feel more comfortable on your bike the more you ride it. On downsizing to a 52... The actual difference will be about 1cm in your top tube and 10mm in your handlebars. This is not a significant number that will lead you to having a better fitting bike. I suspect quite seriously you just need to get used to riding the bike.

Not necessarily... I have a tall elf length legs and a long torso I'm 5"10. I can't stand over a 56 comfortably. The human body is very rarely proportionate like that. Actually in my case the difference is having a seat post that would be at the maximum insertion point vs. having a comfortable bike to ride that I do have with this frame which is why I keep spending money on it.
