Final answer:
The correct answer is a) Morton's neuroma; Metatarsal pads and shoe modifications.
Step-by-step explanation:
Morton's neuroma; metatarsal pads and shoe changes is the right response (a). Morton's neuroma is a condition in which there is a pinched nerve in the foot, typically between the third and fourth metatarsal bones. This can cause pain and crepitus when squeezing the metatarsal joints. Metatarsal pads and shoe modifications, such as wearing shoes with a wider toe box, can help alleviate the symptoms and provide relief. When squeezing the metatarsal joints, a runner who experiences pain and crepitus is probably suffering from a foot structural issue like metatarsalgia or a metatarsal stress fracture. Treatments for metatarsalgia, which is frequently brought on by the pressure exerted by wearing high heels, include relaxation and wearing supportive footwear. Correct diagnosis is essential since various foot ailments call for different kinds of care.
