Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it it seems that due to severe blow there has been rupture of blood vessels leading to accumulation of blood in the soft tissues leading to formation of large
bruise..
Swelling seems to be due to accumulation of inflammatory fluid in the soft tissues as a result of inflammation of soft tissues secondary to traumatic injury..
Numbness is due to injury to periferal nerve endings due to direct blow to them..
Pain is due to inflammation of soft tissues as wellas injured nerves..
I would suggest you to do cold compresses over the injury site..
You can take anti inflammatory painkiller like
Ibuprofen..
You can apply
analgesic ointment like
Diclofenac..
Elevate your leg while lying down..
You can take Vitamin B complex supplements as it helps in repair of nerve..
Don't do Excessive physical work as it can increase Inflammation and swelling..
In case of no improvement in a week consult an Orthopedician and get evaluated..
Hope this information helps..
Thanks and regards.
