My daughter has had eight weeks of swelling in the fifth metatarsal phalangeal joint between the fourth and fifth metatarsal heads. X-rays are negative for fracture her lab work was negative from the rheumatologist. She had an MRI which showed inflammation around the fifth metatarsal head. She has a mild bunionette deformity on that foot. She doesn t pronate when she walks her gait is normal. We are stumped!
