Hi,
Welcome to ehealthforum,
The symptoms that you describe could be suggestive of possibility of vaginal infections, PID, vaginismus, vaginal spasm (at the time of orgasm), possibility of endometriosis etc. Consider getting a repeat vaginal swab/smear test done along with PAP smear test. If the smear results come out clean, then go ahead with further tests done to rule out chances of vaginismus, endometriosis etc. Further treatment measures would be directed based on the examination and investigation results. Drink plenty of water. If infection is detected, get your partner also treated simultaneously to prevent re-infection and avoid having intercourse while being on treatment course. Avoid vaginal douching, use of harsh soap or perfumes in the area (vagina has its own mechanism of cleaning itself. Use of these products harms the normal bacteria of vagina and it becomes susceptible to infection). Use loose cotton undergarments and avoid tight fitting clothes (make sure your undergarments are washed properly and have no traces of detergent in them).
Take care.
