I'm not surprised you can't find much on the internet about PN and Ledderhose ( plantar fibromas). Less than 1% of the population has LD, so it would be tough to say how many of those have PN. My PN started nearly right away when I found the lump on my arch. I found a doctor in TX who has been doing enzyme injections for about 20 years with some reported good success. If it doesn't hurt, don't do anything as surgery is the worst thing for it and it will come raging back. If it does hurt to the point of not being able to walk on it, consider the hyaluronidase injections.

Sorry to see you are not feeling well. Right now I have a good day or two at the most. It's hard to get used to.
