60. 話說回來,病人自己買藥來吃可以嗎?
• Can I treat myself? — Many women would prefer to
avoid seeing their healthcare provider. However,
self-treatment can delay getting the correct
diagnosis, be costly, or even cause worsened
symptoms. In most cases, a physical examination
should be performed before any treatment is used.
In particular, you should not douche to get rid of the
discharge because douching can make the
discharge worse if it is due to an infection.
