Welcome to Health Care Magic.
Thanks for your query.
This pain may be inadequate calcium intake during pregnancy
Take calcium tablet 500mg twice daily for a month and then take one tablet a day for over 3 months.
Apply a good pain -killer gel over the painful area.
Better avoid pain -killer medicines.If pain is more then take paractamol 500mg as SOS.
If pain do not subside after this basic treatment then consult your family physician for clinical examination and investigation for the better management.
