welcome to hcm forum
as per your history you have ankle sprain
means lateral collateral ligamnet injury
which was partial. it takes 4-6 weeks for the ligament to heal.. since it is just 4weeks old i would advised you not to strain the ligament by sitting cross leg or by twisting the ankle inward. the ligament is healing to get it strength back it will take some more time.
meantime you can meet a physiothterapy who would to the rehabilitation
of the ankle sprain
wishing you early recovery
