Hi, I hit my shin very hard in a football game a week ago.  There is a large bruise and scratch on my shin.  Also, there is blood pooling on my ankle.  The area where I was hit feels numb to touch.  It also stings when it gets hit or after I get done sprinting.  What is causing this.
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint it is 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 peripheral nerve endings due to direct blow to them. Pain is due to inflammation of soft tissues as Wells 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 Orthopedic and get evaluated. Hope this information helps. Thanks and regards. Chat Doctor.
