My vagina lips started hurting 2 days after unprotected sex. A burning sensation. I have no discharge, no bumps, swelling or redness.
I look completely normal.
After a few days of discomfort, I go to the clinic. They diagnose me with a UTI, per my urine test. After a few days of being on an antibiotic, I felt better. Now it has all returned. They are burning. No itching.
Should I go back to clinic? Or wait to I have finished antibiotics?
Also, initial tests showed no STDs. (Heroes and HIV tests take longer for results.)
Basically, I feel like I'm losing my mind (or maybe paranoia) because I look fine! I just feel it.
Any suggestions?
Is this really a yeast infection?
