I am 54 yrs .A week ago I awoke to this area on by left shin area that feels like I have bruised it. teh area is still tender to the touch. I don’t see any bruise but it feels like I walked into a metal pipe in the dark and it left this awful bruise with pain. Well here I am a week later and it still fells about the same. Also there is some swelling around it. I have not had it checked by a doctor but wondering if I should. Any thoughts?
