I recently joined the enlisted into the National Guard and my ship date is May 9th.  In the frist week of april, I was running (In worn out shoes)  and when I got about half a mile both of my shins were in extreme pain.  A week later my right leg felt normal as my left leg was still in pain.  Yesterday it felt good enough so I bought some good shoes and went for a run.  A half mile later extreme pain again (This time only in my left shin).  My question is if this "condition" would delay my entry?  Is there anything I can do?
