Welcome to Health Care Magic.
I have gone through your query.
Based on the information provided you might have injured the ligament around ankle.
especially around ankle heal slowly as ankle is the weight bearing joint. Usually the ligament injuries may not show any swelling or bruising. You should have taken the medicines as your doctor prescribed.
Now that you have started experiencing the pain again, it suggests that the injury has not healed.I would recommend you to take anti inflammatory preferably the combination of a NSAID( like Diclofenac
or acelofenac) and serratio
peptidase after consulting your doctor. Anyways get an x ray
done to rule out any bone injury
. Meanwhile use crepe bandage around ankle as this would limit excess movement at the joint and there by reduces pain.
Wish you good health
