I am mid 50 s, female, diabetic, but no problems with that. A week ago I was trimming hedges and kicked a landscape boulder hard. My big toe hurt. Now the skin beneath the base of the toe is black back more than a quarter inch, the nail is fully gray, and kind of puffed out over the black skin at the base of the nail but I don t see any infection. Is tender under the nail about 2/3 of the way up . Do I seek medical attention or just wait this out?
