Welcome to HCM
We understand your concerns
From the edescription you provided there could not be any fracture
. The swelling might have happened becuse of internal bruise
or blood clot due to fall. Both can be taken care of by body itself with some external assistance.
Use warm water to sponge the area atleast thrice daily. Use olive oil or sesame seed oil to massage
half an hour before hot water sponging. Redcuce the use of that leg for the period.
If no relief even after three days, contact a general physician for further advice.
Get well soon
