Hi all, Been having this problem for quite aometime now and haven't been able to figure it out. The facts: - The front of my shins are all bumpy. I played hockey(field) and football(soccer) throughout school and university and got knocked on my shins all the time. - When I run a long distance 10 Km or so, I almost always get sore shins. They don't normally hurt while I run (sometimes they do and I have to stop), but are sore for a few days after esp. when I try to massage, stretch and relax my shins. - I don't get any pain on my shins during my boxing training, it only happens on long runs. Questions: - What are the bumps? Is it the bone or is it tissue deposits? - Is the pain because of the bumps or is it just that my running technique is putting stress on my shins? - I am interested to learn MT or kick-boxing in the near future. Will my shins pose a problem? I ran yesterday, and right now any pressure on my shins is painful. I definitely won't be able to tolerate a kick or a block. - Most importantly how can I fix the problem? I know it is a lot to ask with my ambiguous observations, I am going to see a doctor about it this coming week. I was just curious to know if anyone else on the forum has a similar problem and if they know how to overcome it and strengthen my shins. Thanks in advance and best regards to all.
