The height of arches and the shape of the toes vary from person to person. It is the deviation from normal arches and toe position that lead to foot problems.
Osteochondromas are benign bone tumors
under the toenail. They form in the bone beneath the toenail. An osteochrondroma accounts for about half of all benign bone tumors
, occurring mostly in children and young adults. Unless they cause irritation to the surrounding tissue, they are generally not very painful.
Sometimes, they can deform the toenail and cause an ingrown toenail. In some cases, they are removed surgically, but can recur even after the procedure.
