My 5 year old daughter has a lump which has suddenly appeared on the outside of her left foot. It is directly where the little toe joins the foot purtruding out wards. It is red and sore and hard and the size of a small marble and she has had no direct trauma to the foot. However over the last week and a half her second toe, next to big toe on the same foot became swollen underneath, red, purple and bolbus not extending past the first knuckle joint and not on top just underneath and a little at the tip so I took her to the dr for that when it did not get better on its own but they just gave an antibiotic script without determining the cause, to use if it did not go away. The swelling has reduced but still a little red and purple bits? I have not given the antibiotics yet.
