my feet seems to 'grow fat or big' after giving birth... now can't wear covered shoes... just hurts (even for those shoes I could wear during pregnancy)... any mummies experience the same as me?

I went up 2 shoes size after giving birth! All my old shoes cannot wear anymore. My feet also seems much wider than before and alot of those narrow shoes all cannot wear. I wonder if having really swollen feet due to water retention during pregnancy led to this...
