If it is large, it may be appropriate to pop the blister with a sterile needle, by piercing it several times at its roof, then to drain the fluid as thoroughly as possible before applying an antiseptic, and bandaging. If the area appears infected or excessively inflamed, see your podiatrist. Keep your feet dry and wear a layer of socks as a cushion. Corns ordinarily form on the toes and calluses on the soles of the feet, but both can occur on either surface. Never cut corns or calluses with any instrument, and never apply home remedies, except under a podiatrist's instructions.
Daily hygiene is essential.
Change your shoes daily to let each pair air out, and, if your feet perspire heavily, you may wish to change your socks more than once daily. Stress also can result from a bruise incurred while walking or jumping on hard surfaces or from poorly made or excessively worn footwear. Inserts designed to take the pressure off the heel are generally successful. Heel spurs are bony growths on the underside, fore part of the heel bone. Pain may result when inflammation develops at the point where the spur forms.
