My 8 year old son hurt his ankle three weeks ago in a soccer game, after two sets of xrays showing no fractures or obvious growth plate concerns, his orthopedic doctor ordered an MRI. He was diagnosed with a mild bone contusion or bruise. The mri showed no issue with ligaments or tendons and confirmed no fractures or growth plate concerns. He has been in an immobilizing walking brace for two weeks now, going on three.....How long does something like this typically take to heal up in a child? There is minor swelling on the outside of the ankle bone and minor tenderness currently. Thanks for any help or advice
