Among them, pain in the armpit may appear and worry you. Is it simply an effect of hormones? When should you consult a healthcare professional? How can you relieve the pain?<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong>Armpit pain during pregnancy<\/strong>: let\u2019s take a closer look.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Common causes of armpit pain during pregnancy<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Armpit pain is a common symptom during pregnancy. It can have several causes, ranging from simple physiological reactions to situations that require medical attention. <strong>Here are the main causes to know<\/strong>.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Armpit pain during pregnancy: hormonal changes<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">During pregnancy, the rise in hormones affects your tissues, especially those in the breast and axillary regions (the area under the armpit). <strong>Under the effect of estrogen and progesterone<\/strong>:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Breast tissues prepare for breastfeeding, <strong>thicken and become more sensitive<\/strong>. This growth can extend to the armpits, where accessory breast tissue sometimes naturally exists.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Small skin lesions such as molluscum fibrosum gravidarum may appear: these are small <strong>benign growths<\/strong> that can develop under the armpits.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">These changes can make the axillary region painful, especially when touched or if clothing rubs against the area.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Armpit pain during pregnancy: swollen lymph nodes<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Axillary lymph nodes play an essential role in immune defense. During pregnancy, the lymphatic system is particularly active and may lead to:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Increased lymphatic volume<\/strong>: due to hormones and the body\u2019s adaptation, it is not uncommon for lymph nodes under the armpit to become larger or more sensitive.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>A reaction to a mild infection<\/strong>: a simple cold or minor skin infection can cause temporary lymph node inflammation, making the area painful to the touch.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">Armpit pain during pregnancy: other possible causes<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In addition to hormonal and lymph node causes, other factors may explain armpit pain during pregnancy:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Skin infections<\/strong>: a minor infection, for example due to an abscess or folliculitis (after shaving or hair removal), can cause localized pain with redness or warmth.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Cysts<\/strong>: the appearance of benign cysts is common and generally harmless.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Muscle pain<\/strong>: postural changes, carrying heavy items, or muscle tension related to pregnancy may cause pain that radiates to the armpits.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Rest assured! In most cases, it is neither a tumor nor breast cancer but rather a normal response to pregnancy. Simple irritation due to sweating, heat, or an ingrown hair can also sometimes be a source of pain. <strong>In all the situations listed, the condition is temporary<\/strong>. However, cases that require consultation with a healthcare professional will be discussed later in this article.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Want to learn more?

Fortunately, a few simple adjustments can make a real difference. Here are some practical tips to reduce discomfort in the axillary area:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Adopt gentle and suitable hygiene<\/strong>: choose a mild soap without fragrance or alcohol to avoid irritating the armpit skin, which is particularly sensitive during pregnancy. Avoid harsh deodorants or those containing endocrine disruptors. Choose the most natural option possible, preferably organic.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Wear comfortable clothing<\/strong>: opt for loose tops made of breathable cotton that do not irritate the axillary area. Avoid tight straps or synthetic fabrics that can increase moisture and promote infection.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Moisturize regularly<\/strong>: apply a hypoallergenic moisturizing cream after showering to reduce skin dryness and prevent the appearance of small lesions or benign cysts.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Use soothing compresses<\/strong>: if the area is painful or swollen, apply a warm or cold compress to the armpit for a few minutes several times a day. If the pain persists, it is best to consult a healthcare professional.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\"><strong>Good to know<\/strong>: in case of excessive sweating due to hormone-related hyperhidrosis, wash and dry your armpits thoroughly to prevent irritation and reduce the risk of infection.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong>Warning<\/strong>: many anti-inflammatory medications or ointments are not suitable during pregnancy. Never use topical or oral anti-inflammatories without advice from your doctor or midwife.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In summary, armpit pain during pregnancy is a common symptom, most often related to hormonal changes, breast tissue modifications, or a benign reaction of the lymph nodes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although this discomfort can be inconvenient in daily life, it is generally temporary and harmless, and is part of the many physiological changes that accompany pregnancy. However, staying attentive to unusual or persistent signs allows you to act quickly if necessary.<\/span><\/p>\n<p>**<\/p>\n<p>Cr\u00e9dits photos : Rawpixel | micens | Zinkevych_D<\/p>\n<p><span style=\"font-weight: 400;\">This text was translated from French by an artificial intelligence.
