hello , im currently a 19 year old active man who just enjoys sport , however i suffer from a very weak shin . since i was in year 5 to 6 (10 - 11) i used to receive plenty of hits onto my shins during football games in attempt to take the ball away from me . since then i would have very weak and fragile shins , that , a light hit during a game would create a painful swelling and bump , the harder the hit the bigger the lump , this would be continuous , i now wear shin pads no matter what the occasion when playing the football game , but even shin pads do not cover my whole shin and tend to receive hits in exposed areas of my leg . my instincts tell me it cant be shin splints , because i can run for long distances and not feel pain on my leg . do you have any possible ideas of what it might be , it would really be helpful
