Can a vaginal infection cause burning during urination?

Question

Hi doctor,

I have been experiencing itching inside my vagina. A few days ago, I also noticed a burning sensation while urinating, along with a pus-like discharge during urination. Additionally, there is slight swelling on the right side of the vaginal area.

I began taking Cetirizine and Clotrimazole tablets, as well as Clotrimazole cream. However, the itching has become significantly worse despite this treatment.

What could be the underlying cause of these symptoms?

Please help me.

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

Thank you for the detailed information, which is very helpful. Based on your symptoms, here is a medically informed perspective:

Probable diagnosis:

You are likely experiencing a vaginal yeast infection (candidiasis) or possibly a mixed infection. This conclusion is based on the following reported symptoms:

Key symptoms:

Itching inside the vagina (worsening).
Burning during urination.
Pus-like discharge.
Swelling on one side of the vulva.
Recent use of Clotrimazole (an antifungal) and Cetirizine (an antihistamine).

What this may indicate:

Vaginal candida infection (yeast infection):

Clotrimazole is commonly used to treat yeast infections, but in more severe or recurrent cases, it may not be sufficient, especially if only topical or oral formulations are used without adequate coverage.
The worsening of symptoms despite treatment suggests either resistance, incorrect application, or an alternative diagnosis.

Bacterial vaginosis (BV) or a sexually transmitted infection (STI): The presence of pus-like discharge, burning, and localized swelling could point to:

Bacterial vaginosis (BV) requires treatment with antibiotics such as Metronidazole, not antifungals.
STIs such as chlamydia, gonorrhea, or trichomoniasis.
A Bartholin’s gland cyst or abscess is a swelling that is localized, painful, or tender.

Recommended next steps:

Immediate actions:

Discontinue the use of Clotrimazole if there is no improvement after several days.
Avoid self-medicating further until a proper diagnosis is made by a healthcare professional.

Consult a gynecologist or visit urgent care for:

A detailed pelvic examination.
Vaginal swab for microscopy and culture.
Urine tests and possibly a full STI screening.

In the meantime:

Wear loose-fitting, breathable cotton underwear.
Avoid using soaps, douches, or scented feminine hygiene products.
Apply cold compresses for temporary relief from itching.
Stay well hydrated.

Potential treatment options (after confirmed diagnosis):

For yeast infections: Oral Fluconazole or high-strength antifungal suppositories.
For BV or STIs: Antibiotics such as Metronidazole, Doxycycline, or Azithromycin.
For Bartholin’s cyst or abscess, drainage may be required along with antibiotics.

Feel free to ask if you need any more clarification or help with your questions.

Thank you.
