How long will i have to wait untill i can dance again after foot fracture?

Depends: Where was the fracture, what bone, severity of the fracture. A guess is about 6 weeks depending on what type of dance.

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.

Follow up x-rays: You should avoid dancing until you have significant radiographic signs of healing. Bone healing usually takes about 4-8 weeks.
