Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain it seems that due to
injury there is rupture of small superficial blood vessels leading to spillage of blood into the soft tissues leading to
Hematoma formation and bruising..
Numbness can be due to injury and inflammation of terminal nerve endings at the site of injury..
I would suggest you to ice packs or cool compresses over the injured area..
You can also apply a
heparin gel over the area of injury for faster fading of bruising..
You can also take painkiller like
Ibuprofen for relief from pain and inflammation..
Elevate your leg while lying down..
In case if there is pain on putting weight over the knee consult an Orthopedician for an x ray to rule out for fractures..
Hope this information helps..
Thanks and regards.
