Knots on bottom of feet
For the past year I’ve had knots developing under the skin of the bottom of my feet.
They can appear at any time of the day, and can last for a few hours or an entire day.
The skin usually becomes a little red where they’re located.
I can’t really tell if it’s muscular, connective, or osseous in nature, but they’re dense and painful.
They primarily appear on the ball and lateral part of the foot (not the arch), and sometimes where the heel meets the arch, but never directly on the heel or toes.
Walking barefoot on hard or cold surfaces seems to aggravate them, and cause them to appear.
The only thing I can think of is that I wore a really terrible pair of house shoes for the past couple of years, that had a very thin sole.
I stopped wearing them, but I still have this problem.
