Preparing for a June 28th fight and just started getting severe pain in my right shin whenever I have any contact on it in sparring. I've been training since last August and have not had pain like this before. It had been tender for the past couple of weeks but nothing like this. The pain is very strong and I am terribly concerned that it may be a hairline fracture. There is only light bruising, no swelling, and after the pain subsides I can walk on it. I am also concerned that whatever has happend may prevent me from fighting on the 28th. Anybody out there have a similar problem? Any suggestions on what to do? Any information you could provide would be helpful. Thanks.
