 [ Symptoms ] i hurt my neck 2 years ago is aps therapy good [ Disease ] so sorry to hear you are going through this ouch unfortunately soft tissue injuries like sprains can take a long time to heal the fact your ankle is still black and blue after a week tells me this was a pretty serious sprain it is going to take your body quite awhile to repair the damage keep resting the ankle keep elevating it as much as possible and follow the other instructions you were given if you are not able to bear weight on the ankle within the coming week i would recommend going back to the doctor it is always possible there is a little fracture in there that could not be seen on x ray due to swelling when you were first examined assuming you had an x ray initially  i know it is hard to be patient but keep in mind that trying to rush the healing process can actually aggravate the injury    which will take even longer to heal i wish you all the best
