I had a small injury with my leg 5 weeks back, I was riding my quad and my leg got trapped under it and it got bruised pretty good, I have been trying to keep track of the area that was bruised and since 3 weeks ago I have had a stiffness in my leg in that area, I have really no feeling in that area except skin contact, its like a hard numb spot about 1in. by 2in under my skin, what should I do?
