Thanks for asking me to respond. If you have injured your able earlier then it could possibly be an old injury that has not completely healed. Am xray will reveal any old fractures while an MRI will reveal old ligament or cartilage injures. Most ideal would be for you to visit an ortho surgeon who can clinically examine the ankle and advice the appropriate xrays and/or scans. In the meantime, you could take pain meds and wear an ankle binder in order to protect the ankle from further injury. I cannot prescribe meds as Practo prohibits me from doing so. Good luck.
