Are you just grooming your feet? I keep my toenails cut way short and I cut the callouses off the sides of my feet but I do it for cosmetic reasons only. If it is for cosmetic reasons then no it is not SI. Shoot there are so many nifty things we can do that are self injurous that leave no permanent marks why add self grooming acts to the list?
