How to describe medical symptoms in English?

Let me take a look. When did you first notice it? Have you been exposed to any new plants, foods, or products?

让我看看。你什么时候发现的？有没有接触新的植物、食物或产品？

This looks like contact dermatitis — possibly from poison ivy or poison oak. The rash appears as red, itchy bumps in a line pattern, which is typical of plant contact.

看起来是接触性皮炎——可能是毒藤或毒栎引起的。皮疹呈红色、发痒的疙瘩，呈条纹状，这是植物接触的典型表现。

No, it's not contagious. But wash all the clothes you were wearing that day — the plant oil can stay on fabric and cause a new reaction.

不会传染。但要清洗你那天穿的所有衣服——植物油脂会残留在织物上引起新的反应。

I'll prescribe a topical steroid cream. Apply it twice daily. Take antihistamines for the itching. Avoid hot showers — they make it worse. Cool compresses will help.

我给你开外用类固醇药膏。每天涂两次。服用抗组胺药止痒。避免热水澡——会加重。冷敷会有帮助。

Usually 1 to 3 weeks. The cream will speed up healing and reduce itching. Come back if it gets worse or you develop fever or pus at the rash site.

通常1到3周。药膏会加速愈合并减轻瘙痒。如果恶化或皮疹处出现发烧或脓，回来复诊。

Are you having any difficulty breathing or swelling in your throat? This is important.

有呼吸困难或喉咙肿胀吗？这很重要。

Do you know what triggered it? Did you eat anything new, take any new medication, or get stung by an insect?

知道什么引起的吗？有没有吃新的食物、服新的药物，或被昆虫叮咬？

Shellfish allergies can develop at any age. I'm going to give you an injection of epinephrine as a precaution, and IV antihistamines. We need to monitor you for at least four hours.

贝壳类过敏可以在任何年龄发生。我要给你注射肾上腺素作为预防，以及静脉抗组胺药。我们需要至少观察你四小时。

Allergic reactions can have a second wave — called a biphasic reaction — hours after the first. It's safer to monitor you. I'll also prescribe an EpiPen for you to carry.

过敏反应可能有第二波——叫双相反应——在第一次之后数小时发生。观察更安全。我还会给你开一支肾上腺素笔随身携带。

Of course. Remove the safety cap, press firmly against your outer thigh — it works through clothing — and hold for 10 seconds. Then call 911 immediately.

当然。拔掉安全帽，用力按在大腿外侧——可以隔着衣服——保持10秒。然后立刻打911。
