Pain underneath left pinkie toe; able to flex toe up and down, but when pressure is put on left interior side of that area, pain is unbelievable. Cannot wear a shoe, sandal is what I am using now, but any pressure to that area pushing it inwards towards my other toes, causes extreme unbearable pain. Did not fall, stumble, stub it, nothing; had walked my usual 2 mile walk with my winter walking boots on for two days prior. No visible sign of any injury; not a corn or a bunion; no redness.
