I noticed back and chest pain for the last week since I've been trying to walk straighter.
I always used to slouch all my life now at 29 im trying to walk upright and my back has been killing me.
I also push a rolly cart this past week for 7 days an front part of my chest has been hurting.
they rolly is a computer on wheels. I also carry my purse and laptop which is heavy as well.
Any suggestions?
