As others have already replied (below) before I saw your message, the symptoms came on too soon for chlamydia; if any STD at all was responsible, gonorrhea fits better with the short incubation period. In any case, you describe a very safe situation from an STD standpoint. STDs are rare in people in their 40s, and you imply both you and your partner/friend don't have high risk sexual lifestyies. And indeed if she was taking antibiotics, there is little chance of transmitting anything to you. Finally, in the very slim chance your doc was right about chlamydia, the azithromycin would have cured it for sure, regardless of the slightly atypical dosage schedule.
Men rarely get the symptoms you describe from a yeast infection. I would be more suspicious of some sort of chemical irritation. Statistically, herpes is always a slight possibility, but unlikely without penile blisters/sores.
If your symptoms resolve--which probably they will within a few days--just forget the whole thing. If they persist, of course return to your doc for further evaluation. In the meantime, I wouldn't lose any sleep over this (from a medical standpoint--the relationship issue is your responsibility, of course).
Good luck-- HHH, MD
I know my symptoms might be consistent with a yeast infection as well, but developed no visible signs other than the burning/frequent urination sensation..and I would've suspected the sensation to get worse in taking the antibiotics, which it hasn't...
I appreciate your answers and time taken in this matter...
I am not a Dr but until he replies, maybe this will help.
I expect that the Dr. will say that the dose of meds you took will clear up the Chlamydia no matter how you took it. That pill is designed to be taken over a short time unlike other antibiotics which you take over a week. I have read that sometimes the "after effects" of Chlamydia could last a few days even after the infection is gone.
Did your Dr test your urine for Chlamydia before you took the meds? If not, you will not be able to determine if you ever did have anything in the first place.
See what the Dr says to be sure but I bet you are going to be fine.
Hope this helps
1) Your symptoms are most likely not due to chlamydia, simply because symptoms of chlamydia don't show up "within 48 hours." It usually takes at least a week for symptoms to show up. Such isn't the case for gonorrhea, where symptoms can show up as short as two days. Although negative WBC may indicate that your urine is not infected, it doesn't necessarily tell you if you have been infected with gonorrhea or chlamydia. However, if you were infected with chlamydia, a 1gm dose of zithromax would have cleared it up, which you took on the second day.
2) Your symptoms can be due to her yeast infection. YOu will know for sure once she gets tested.
