Hi
Welcome to the MedHelp forum!
Pain in the pelvis and vagina can be due to infection, pelvic inflammatory disease, UTI, STD, uterine fibroids, urinary bladder infection or cystitis. If you do not have any discharge and there is no other symptom then it can also be due to pinched nerve (either pudendal or spinal). These conditions are broadly classified as chronic pelvic pain syndrome. The intensity of pain depends on the degree of inflammation and thus compression. This can vary. Take care!
