I just want to make sure we're talking aboutthe same thing. Did she say the white blood cells were high in the cervical swab? Or did she run a blood sample and your overall white blood cell count is high?
A lot of white blood cells on a cervical swab (pap smear) mena that your cervix is inflammed. Some inflammation is normal. A lot of inflammation could indicate an infection or something else. Given that you have no symptoms I'm surprised she didn't order specific testing for chlmaydia and gonorrhea.
Did your doctor send a pap smear off to the lab so a trained pathologist can look at it? Pap smears can be tested for clamydia and gonorrhea. You should call the office back and ask if that was done.
If you really do have Chlamydia or Gonorrhea, then your husband also has it. To treat the infection both partners have to be treated with antibiotics at the same time. Otherwise he'll reinfect you.
Also doxycycline isn't going to treat both of those infections. It should treat Chlamydia, but won't get gonorrhea. Gornorrhea needs a different type of antibiotic. An antibotic callled azithromycin works for both infections.
I hope I haven't overwhelmed you. From your post I don't think your doctor is communicating well with you about why she is treating you with doxycycline. I think its worth calling back today and making sure you know what your doctor is thinking.
