In anatomy, a sesamoid bone (/ ˈ s ɛ s əm ɔɪ d /) [1] [2] is a bone embedded within a tendon or a muscle. [3] Its name is derived from the Greek word for 'sesame seed', indicating the small size of most sesamoids. Often, these bones form in response to strain, [4] or can be present as a normal variant. The patella is the
Stage 2: Decreased local edema, with coalescence of fragments and absorption of fine bone debris. Stage 3: No local edema, with consolidation and remodeling (albeit deformed) of fracture fragments. The foot is now stable. Atrophic features: "Licked candy stick" appearance, commonly seen at the distal aspect of the metatarsals; Diabetic osteolysis
Symptoms include inflammation and pain. Sometimes a sesamoid bone is fractured. This can be difficult to pick up on X-ray, so a bone scan or MRI is a better alternative. [1] Among those who are susceptible to the malady are dancers, catchers and pitchers in baseball, soccer players, and American football players. [2] [3]

Any part of the foot can be affected by diseases, with symptoms ranging from mild aches to more serious pain hindering one's ability to walk or bear weight. Most minor cases of foot pain can be responded to by home care treatments. However, when severe pain is present, medical attention is required as it is a disabling condition.
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
Osteomyelitis, a bone infection, may leave the adjacent bone with exostosis formation. Charcot foot, the neuropathic breakdown of the feet seen primarily in diabetics, can also leave bone spurs that may then become symptomatic. They normally form on the bones of joints, and can grow upwards.
Freiberg disease, also known as a Freiberg infraction, is a form of avascular necrosis in the metatarsal bone of the foot. It generally develops in the second metatarsal, but can occur in any metatarsal.
