Hello - I have had lumps on my feet before. My podiatrist ordered xrays and it was a tendon that had ruptured. From what I can understand, they can just let go and curl up. He said he could do surgery but it wasn't necessary unless I was in pain from this. It does not bother me and the lump is actually gone now. I think it jumped over to the other foot for awhile. I think to some extent, this is part of the disease. My feet do not look like they use to and buying shoes that fit, are comfortable and that will actually stay on my feet is a challenge.

Good luck.

Cheryl
