I fell yesterday landing on the left outer area of my left shin.  I have arthritis in that knee but more towards the inside of the knee.  My skin felt like it had road rash, but the skin didnt break is just rough (I had on jeans, so thats probably why).  Now it is numb.  Should I be concerned and get this checked out, or is this normal?
Hi I am Chat Doctor. .  In my opinion, i don't won't you to be worried and for many patients I suggest icing it for the first 48 hours, NSAIDs painkiller like Advil when needed, massaging it with topical gels, elevation your left leg on a pillow and avoid bending will be effective for such cases. For the numbness actually its quiet rare but happens when trauma or the swelling affect the nerve supplying this area which will subside when swelling decreases. Otherwise, I recommend X-rays to exclude minor fissures or fracture on your shin-bone. Please click THANK YOU and consider a 5-star rating with some positive feedback if the information was helpful.
