I have bunion on my right foot. I hike once a week for 3-5 miles only. It seems to me that my big toe on the right side where the bunion side is has changed its LOOK and formation of its nail..
I used to have all STARIGHT/flat nail plates of my fingers and toes (kind of sitting right on top of each nail-bed). However, the nail-plate of my right big toe seems to be sunken, so that the tips of the toe seems to be rounder and its skin there is shiny.
Right toe:
Compare left and right (although the left one doesn't look flat at all, perhaps due to some weight pressure on the foot):
Any concerns? Thanks
