Is It Safe To Walk On Fractured Ankle?

Hi. My name is Danny I went to a urgent care 2 days ago to get my ankle looked at. The doctor X-rayed me and said its just sprained. Well today i got a phone call from his nurse who said he reviewed the x-ray futhar and there maybe be a small fracture and i need to see a orthopedic docotor to be safe. I dont have alot of money i may not be able to see one. Am i safe to walk on it?
