Omgee! It must have been so uncomfortable and unbearable to wear tight shoes for that long! I've had a similar experience like you! And it wasn't nice at all. I started to notice how it affects the way I walk and my body postures. It was an unpleasant moment to be wearing a wrong shoe size!
And I always make sure I wear the right shoe size for my feet to avoid such incident to happen again! Great thorough research on the consequences of wearing wrong size of shoes! That explains well why I experienced discomfort and pain at that time. Haha
