Sesamoiditis is any irritation of the sesamoid bones.
Sesamoid bones are tiny bones within the tendons in the foot that run to the big toe.
These bones function as a pulley, increasing the leverage of the tendons controlling the toe.
Ball of Foot
The most common symptom of sesamoiditis is pain and swelling in the ball of the foot. The pain often occurs on the medial or inner side.
The pain may be constant, or be aggravated by any movement of the big toe joint. The pain is often accompanied by swelling throughout the bottom of the forefoot.
Sesamoiditis is usually caused by repetitive, excessive pressure on the forefoot. Other causes include increased activity, stress fractures, high arches, or having a bony foot. If you have a bony foot, you may not have enough padding to protect your sesamoid bones and tendons.
Rest and icing the soles of your feet. Do not apply ice directly to the skin, but use an ice pack or wrap the ice in a towel.
Wear soft-soled, low-heeled shoes. Stiff-soled shoes like clogs may also be comfortable.
Orthotic with metatarsal pads may often help to relieve stress from Sesamoiditis.
