Dancing. Could you dance before the foot injury ? Bone healing usually takes six to eight weeks. Provided the bone is aligned appropriately. See your podiatrist for eval and treatment rccs.
Foot Fracture. Good question....But, which bone, what fracture, how was it treated. Ironically, this all makes a big difference.... Weeks, months , never. See a specialist and get an x-ray...Then ask him the same question...He will know much more....
Follow up x-rays. You should avoid dancing until you have significant radiographic signs of healing. Bone healing usually takes about 4-8 weeks.
Depends. Where was the fracture, what bone, severity of the fracture. A guess is about 6 weeks depending on what type of dance.
