淋巴结是免疫系统的关键部分。它们从身体过滤外来物质并储存白细胞，称为淋巴细胞。淋巴细胞对抗疾病和感染。

You have hundreds of small bean-shaped lymph nodes throughout the body, including in your:

  • 脖子
  • 腋窝
  • 胸部
  • 腹部
  • 腹股沟

淋巴结肿大那also known as lymphadenitis, in the armpit indicate that your body is responding to an infection, injury, or a disease, like cancer. It’s important to keep in mind that in most cases, a swollen lymph node in the armpit isn’t typically a sign of cancer.

It’s not a symptom to dismiss, either, as it may be a sign of a condition that requires medical attention.

腋下的淋巴结可能很难看到，但可能难以看到它可以用手指感受到它。严重的感染或其他条件可能导致一个或多个节点足够膨胀，以至于您可以看到皮肤下的肿块。

请记住，腋下包含许多节点，因此露出的腋下可能​​发生在腋下，以及腋下附近的上臂的一部分。

In addition to being swollen, an affected lymph node may also be sore or tender to the touch.

To check for a swollen lymph node in the armpit, lift your arm slightly and gently place your fingers into your armpit. Press your fingers against the center of the armpit and then around the front and back of the armpit along the chest wall. Do the same on the other side.

Lymph nodes exist in pairs on each side of the body, and typically only one node in a pair will be swollen. By comparing both sides, it may be a little easier to tell if one is enlarged.

如果淋巴结在身体的多于一部分肿胀，则称为全身淋巴结病，这表明系统性疾病。局部淋巴结病是指一个位置中的淋巴结肿胀。

肿胀淋巴结的位置通常表明问题的原因。例如，颈部淋巴结肿胀通常是上呼吸道感染的迹象。

当腋窝中的淋巴结变得肿胀时，您的身体可能会抗击病毒感染，或其他几种其他条件。腋下肿胀淋巴结的潜在原因可以包括：

病毒感染

常见病毒可以引发腋中的一个或多个淋巴结中的肿胀。他们可以包括：

More serious viral infections that may cause lymph node enlargement include疱疹那风疹那和HIV。

这些病毒也可能导致淋巴结在东北ck to become enlarged, too. In many cases, rest, fluids, and time are all that you can do while your immune system fights off the virus. For certain viral infections, likeHIV那antiviral medications may be necessary.

细菌感染

有些常见细菌感染在手臂或周围的胸壁上，包括staphylococcus和streptococcus，可以导致腋下和身体其他地方的淋巴结放大。抗生素和休息通常足以克服细菌感染。

Immune system disorder

自身免疫性疾病的爆发，如狼疮和rheumatoid arthritis那can cause temporary enlargement of the lymph nodes in an armpit. Treatments vary, depending on the cause, but anti-inflammatory medications, pain relievers, and in serious cases, immunosuppressant drugs may be necessary.

Cancer

某些类型的癌症直接涉及淋巴系统。淋巴瘤实际上源于淋巴腺。Leukemia，血细胞的癌症，可引起淋巴结的炎症和肿胀。

Cancers that form in other organs or tissue may spread to the lymphatic system.Breast cancer那for example, can cause swelling of the lymph nodes in the armpit.

癌症肿瘤附近的一个扩大的淋巴结通常怀疑也是癌症。Cancertreatments vary and may include chemotherapy, radiation therapy, surgery, and other approaches.

Medications

在极少数情况下，某些药物会导致淋巴结膨胀。其中包括：

  • ACE抑制剂，β受体阻滞剂和血管扩张剂以治疗高血压
  • anticonvulsant drugs, including phenytoin and primidone
  • anti-malarial drugs, including quinidine
  • uric acid reducers, like allopurinol

Switching medications or adjusting doses may be enough to reduce side effects like lymph node enlargement.

As your body starts to successfully fight off the infection, the swelling in your lymph nodes should start to diminish.

With a typical bacterial infection, for example, a course of antibiotics should start to relieve lymph node swelling and other symptoms within a few days. A stubborn viral infection could take longer.

If your other symptoms are subsiding, but your lymph nodes remain swollen, tell a health professional. You may need additional treatment or a follow-up exam to see if there are other reasons your lymph nodes are still enlarged.

Because swollen lymph nodes are more often signs of an infection, rather than cancer, you may be inclined to dismiss swelling as a temporary symptom that’ll subside as you get over your infection. In many cases, that’s exactly what will happen.

如果您不确定是否寻求肿胀淋巴结的医学评估，这些迹象可能是看医学专业人士的理由：

  • 无明显原因，一个或多个淋巴结肿胀肿胀。
  • 在2周或更长时间，肿胀持续或变得更糟。
  • The affected node feels hard and immovable when you press on it.
  • 肿胀的淋巴结不痛苦。
  • 您在单独的区域中淋巴淋巴结肿，如腋窝和腹股沟。
  • 你有其他症状，比如：

淋巴结肿大typically get better once your illness has been treated or goes away on its own. To support your immune system as it responds to the infection or illness, you can rest and drink plenty of fluids. If you are prescribed medication, be sure to take it according to the prescribing doctor’s instructions.

如果由于淋巴结肿胀的淋巴结而感到不适或疼痛，您可以尝试申请温暖的压缩以缓解不适。逆逆（OTC）止痛药，例如乙酰氨基酚（泰诺），也可能有助于减少疼痛。

如果您的疼痛变得更糟或无法解决，您可能需要咨询医生进行额外的待遇或测试。

大多数时候，肿胀的淋巴结意味着您的身体的免疫系统正在做出反应感染或其他健康问题的工作。这也意味着您正在处理可能需要治疗的疾病或受伤。

例如，如果你正在冒着寒冷，你会注意到你的腋下淋巴结的轻微肿胀，请注意它几天，看看你开始感觉更好的时候肿胀是否会下降。

无法解释的肿胀或其他严重症状的存在应提示与健康专业人士进行更完整的评估。
