Suggest Treatment For Severe Tightness Of Cervix

I recently went in for a curette to address my issues on very prolonged periods (ranging from 2-3 months continuous bleeding). However, the procedure was unable to be carried out and after coming back from anaesthesia I was admitted for observation as the gynacologist thought he may have done some damage when trying to break through my cervix. The doctor's words were literally 'your cervix is like cement and extremely tight'. Can you make any recommendations that could address this issue?
