Thank you for the query.
Your recent ankle trauma could cause hematoma
or ankle sprain. A weak is long enough for minor traumas to stop causing pain. Otherwise, the trauma might cause some more serious damage and medical attention is required.
So if your ankle still hurts, you should visit your doctor, have simple X-ray of this area and orthopedist consult. If the injured area is swollen, skin is tense and tender when touching it, soft tissues ultrasound
should be also done to rule out blood collection. Such collection can get infected and turn into an abscess
. Moreover, such inflammation can lead to veins thrombosis
So it seems that you have a reason to visit your doctor.
Hope this will help.
