Sorry prama - i can't really help in the advice department because i seem to have the same problem. If he's not sitting under my ribs, he's sitting really low and seems to kick straight into my damn cervix. Either that or he lies all the way across and i get ridiculous pains from the pressure that ends up in my hips because of it. So i certainly know what your'e on about.
If bubby gets really painful, i'll do the ice cold water trick and hope that making him active makes him realign...
Good luck!
