As long as I can remember, I've had leg pains in the exact same spot, being my inner calf. As I've grown up though, it seems that it changes a bit. Its always the same spot, but it now start in one leg (typically my ankle), moves up it, then switches to the other side, down that side, to that ankle.
6 weeks to fully heal to be able to change the earring. cartilage piercings take longer to heal than some other piercings. 6- 12 months is standard. A year is not uncommon either. If you take it out even when it is fully healed and leave it out for too long the hole will close up and this can happen very quickly. http://en.wikipedia.org/wiki/Body_pierci...
Leave the post in your piercing. Until the piercing has healed, taking the earring post out of the hole will only expose your raw tissue to infection. For ear piercings, the healing process typically takes 6-8 weeks.During that time, you must wear the earring you put into your new piercing at all times or risk a painful infection. You should be able to notice results in less than 3 months, but it can take much longer than that to heal the hole completely. 2  Expect mild redness and a dip where the piercing was for a long while afterward.
