Hi,
I have studied your case,
There can be skin discoloration/bruise due to
blunt injury on calf, and there can be
hematoma near ankle.
As x ray is normal indicates
soft tissue injury due to acceleration and
blunt trauma.
I can not compare swelling, but if swelling is there, you need to take rest and use splint or compressive crepe bandage to reduce swelling.
.
On ankle you can apply thrombhophobe ointment.
Watch for increase in redness, infection.
Take precaution to avoid infection around hematoma.
Do not use hot fomentation or
massage.
If required you may need to do blood investigation for prognosis and recovery.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
Take care
