Been dealing with mine since 2004. I’m able to keep it at bay by 1) wearing wide shoes, and 2) wearing a metatarsal pad in ALL of my shoes, including my cycling shoes.
This works for me, but that damn neuroma is there waiting to remind me any time I don’t do both things listed above. On a bike ride last winter, I wore super-thick socks and replaced my normal insoles (with metatarsal pads) with other insoles. That neuroma starting hurting again almost instantly.
The doctor who originally diagnosed the neuroma in 2004 said it would probably get worse over time until I would have to do something more drastic, but thankfully I have avoided anything like surgery or that saline injection thing they can do to kill the nerve.
