I fell off a motor bike at a VERY slow speed on Saturday and hit my lower leg (shin). At first I thought nothing hurt that bad, but when I got back home I realised it did in fact hurt. It is bruised and has a lump that I can feel when I run my hand along my shin, it is visible but only slightly. Probably about an inch in diameter. If I walk around, it is slightly painful but more so if I get up quickly, stamp it, use stairs etc. It s a sharp pain when I do any of the above, but it aches throughout the day. Is it just bruised or should I get it checked out?
