Blistersform when your skin is injured. They tend to show up on your hands andfeet。工具或鞋子的摩擦会导致它们。水泡是您身体保护自己免受进一步损害的自然方式。液体的气泡会收集以缓冲伤口，并使皮肤在愈合的时间下。

水泡的气泡或圆顶就像绷带一样。它可以防止大多数细菌进入伤口。如果皮肤覆盖了泡沫的圆顶断裂，那么您就有患感染的风险。

Infected blisters are often painful. They can also be dangerous if left untreated. A bacterial, viral, or fungal infection that starts in your blister can spread to other areas. It can even result insepsis。This is a life-threatening infection of the bloodstream.

有时很难将受感染的水泡与未感染的水泡区分开。大多数水泡都柔软而痛苦，有些比其他水泡更多。但是，您可以寻找一些可靠的标志。在检查水泡之前，用温水和肥皂洗手，以免引入任何细菌。

With clean hands, feel the area around the blister for signs of:

  • warmth
  • 臭味
  • pus
  • 疼痛
  • swelling
  • holes or peeling skin

如果触摸该区域流血或似乎根本没有愈合时，您也可能会有感染的水泡。

If you suspect that your blister is infected, consult your doctor as soon as possible. There are many different things that can cause infections, so your doctor may perform a皮肤活检。In this procedure, your doctor takes a small tissue sample and analyzes it to determine its underlying cause.

Once your doctor has a better idea of what’s causing the infection, they might prescribe:

  • 口服或局部抗生素
  • oral or topical antifungal medications

They might also perform a quick in-office procedure to drain the blister. It’s very important that you leave this process to your doctor. Doing it on your own can make the infection worse or cause it to spread to nearby areas.

当您等待去看医生时，您可以在家做一些事情来缓解症状并与感染作斗争：

  • Clean the wound.在温水下运行该区域，然后用肥皂轻轻按摩。继续冲洗和洗涤三到五分钟。每天至少重复两次。
  • Soak the wound.将伤口浸入自制盐水溶液中。您可以通过在1杯温水中添加1茶匙盐来做到这一点。
  • 治疗伤口。洗了双手和伤口后，涂上局部抗生素软膏，例如新孢菌素或杆菌蛋白。
  • 治疗疼痛。Take a非甾体类抗炎， 如布洛芬(Advil), to help reduce pain and swelling.

剩下的未经治疗，严重的感染可能开始传播到身体的其他部位。此外，细菌可以进入水泡的皮肤，并导致称为cellulitis。这是一种快速扩散的皮肤感染。如果扩散到您的淋巴结或血液中，它可能会很快成为医疗紧急情况。

在严重的情况下，受感染的水泡也会导致败血症。当您的免疫系统释放的某些化学物质触发体内链反应时，就会发生这种情况。最终，这可能导致败血性冲击。Septic shock is fatal about一半the time. However, most people recover from milder cases of sepsis.

It’s best to see your doctor about any infected blister in order to avoid complications, which can be very serious.

I you notice a red streak moving up your leg, go to the emergency room immediately. This is a sign of cellulitis. It requires immediate treatment to prevent it from spreading too far.

你也应该马上看医生或to urgent care if you have:

  • a fever
  • chills
  • body aches
  • 没有任何愈合迹象的水泡或酸痛

Blisters aren’t usually anything to worry about. Most heal on their own within one or two weeks. While most blisters never become infected, it can be a serious health concern when they do.
