How to describe medical symptoms in English?

Let me take a look. When exactly did you cut it, and how did it happen?

让我看看。具体什么时候割的，怎么割到的？

It does look infected. I'm going to clean the wound, apply an antibiotic ointment, and bandage it properly. When was your last tetanus shot?

确实感染了。我要清洗伤口，涂抗生素软膏，并正确包扎。你上次打破伤风针是什么时候？

We should give you a tetanus booster to be safe. I'm also prescribing oral antibiotics — take one pill twice a day for seven days. Finish the full course even if it looks better.

为安全起见应该给你打个破伤风加强针。我还给你开口服抗生素——每天两次，每次一片，吃七天。即使看起来好了也要吃完全程。

Change the bandage daily. Keep it clean and dry. If the redness spreads or you develop a fever, come back immediately or go to an ER.

每天换一次绷带。保持清洁干燥。如果红肿扩散或发烧，立刻回来或去急诊。

Any drugstore — CVS, Walgreens, or Rite Aid. The ointment is over the counter, but the oral antibiotics require the prescription I'm giving you.

任何药店——CVS、Walgreens或Rite Aid。软膏是非处方药，但口服抗生素需要我给你开的处方。

I'll take a look with an otoscope. Have you been swimming recently, or had any cold symptoms?

我用耳镜看一下。你最近游过泳吗，或者有感冒症状？

It looks like swimmer's ear — an outer ear infection. The ear canal is red and swollen. I'll prescribe antibiotic ear drops.

看起来是游泳耳——外耳感染。耳道发红肿胀。我给你开抗生素滴耳液。

Tilt your head with the affected ear facing up. Put in 4 drops, then stay in that position for about 5 minutes. Do this three times a day for 7 days.

歪头让患耳朝上。滴入4滴，然后保持这个姿势约5分钟。每天三次，持续7天。

Yes, keep your ear completely dry for at least a week. When showering, put a cotton ball with petroleum jelly in your ear to keep water out.

是的，至少一周内保持耳朵完全干燥。淋浴时在耳朵里塞一个涂了凡士林的棉球防水。

Ibuprofen or acetaminophen should help with the pain. If the pain gets significantly worse or you develop a fever, come back right away.

布洛芬或对乙酰氨基酚可以缓解疼痛。如果疼痛明显加重或发烧，立刻回来。
