Suggest Treatment For Ankle Pain Due To An Injury.

Hi, im 15 years old and currently had a fracture to my tiba due to a soccer injury. about 2 weeks ago the doctor released me and said i can start easing myself into playing because my bone is healed and everything. well i go back to run and things like that and my ankle is in SO much pain…i don't know what else to do for it and i dont know why its hurting when i didnt even injure it.
