Hi, I am 28 years female and is sexually active. Since feb I had pain in the pubic bone and no other symptoms. Pain was on/off. Now, pain is rare but I feel weird inside my vagina and feel discomfort while sitting. Went thru a urine culture it's sterile and vdrl and HIV tests as well and those were normal. Can it be a symptom of any other sti or what test or problem would you recommend? Also, no itching or burning. (sometimes happen but very very rare)
