I have a lump on the bottom of my big toe, it is soft and not painful at all.

See a doctor!: Lumps and bumps cannot be accurately diagnosed by a brief written description. See a doctor in person, or consider a Healthtap Prime Consult with a doctor, where you may upload a picture and give a more detailed history. Or see if a Healthtap Concierge doctor or podiatrist can do a virtual consult about this. The most accurate diagnosis, though, is an in-person exam.
