my son who is 16 was in a car wreck in may and his foot was swelled very severely and non wieghtbearing, he went to orthopedic who had put him in a boot for three weeks and then physical therapy. xrays was preformed that showed a small chip in the heel bone. they diagnosed him as having a sprain. he was doing great for two months and now he is back to baseball condictioning and being on his foot at school and this oval shaped knot has popped up on top of foot with swelling and pain. the swelling and pain seem to be worse when he is on his foot. the more active he is the worse his foot is... could they have missed a lisfranc injury or could something else be wrong?
