Can yellow, sour-smelling vaginal discharge without itching heal on its own?

Yellowish vaginal discharge with an acidic odor but no itching may resolve on its own if caused by poor hygiene; however, if it results from inflammation, it will not resolve spontaneously and requires timely examination and treatment. Specific analysis is as follows:

1. Self-resolving cases

Poor personal hygiene habits, such as failure to clean the external genital area promptly after vaginal secretions are released, can lead to yellowish discoloration and an acidic smell due to oxidation. In such cases, specific medications are usually unnecessary. Simply maintaining good hygiene and regular cleaning can allow symptoms to resolve naturally.

2. Non-self-resolving cases

When vaginal infections such as vaginitis or cervicitis occur, inflammatory stimulation causes increased secretion from the vaginal mucosa and cervical glands, leading to yellowish discharge with an acidic odor. Mild cases may not involve noticeable itching. However, these conditions typically do not resolve on their own and require medical intervention. It's important to undergo routine vaginal discharge testing and, based on results, use medications such as Baofukang suppositories, metronidazole suppositories, or nitrofurantoin vaginal soft capsules.

It is recommended to maintain good personal hygiene, change and wash underwear frequently, and seek timely gynecological evaluation and routine vaginal discharge testing to identify the underlying cause and receive appropriate treatment.
