My public bone also pain when after giving birth my first baby,
its hurt every time im over do excersise,walking to much,
i did go to physioterapist,they said not much you can do,because da bone get crack from giving birth....
All you can do are just rest more,take it easy,dont walk to much,that bone gonna get recover by it self...
Now my bone just sometime get hurt...
Hope you get recover soo,i know how you feel...
