I feel like I have knots in the bottom of my feet. The front area (I think that is called the arch?) right below where my toes are. Also feel like there is a knot along the sides of the bottom of my feet. I don't recall this happening before, but I guess it could've and I just don't remember. I HAVE been walking a lot more since January 30th (spring semester started). I have been changing shoes back and forth a decent amount (wedges, heels, sneakers, flats). These are the only things I can think of that might affect this. In other matters... I have a bad diet, and lack a lot of vitamins. I know that for a fact. Has anyone had knots in their feet? If I walk for a while they start to hurt, and if I massage my foot I can feel how much they hurt. What can I do? What could this be? Should I soak my feet or something?
