I was just diagnosed with CRPS this week and I just discovered I have a lump in the arch of my foot. I researched it and it seems like it is plantar fibroma. Are these 2 related in any way. My surgery was done on the outside of my foot and the lump is on the inside. It hurts when touched. I go to my ortho on Friday so hopefully he can give me info on this. I'm really tired of all this.
