My GYN says my cervix is very very tight. Meaning it was difficult for her to do a D&C (I am constantly on my period). So this time she recommended I be put under anesthesia. First of all, what causes a tight cervix, is there anything I need to do about it (I m single, in my late 40s and don t plan on having children), and lastly I m anxious about being under anesthesia but she says I have a low threshold for pain, so that s another reason to put me under. Do you think this is a good idea?
