That sudden pain under your left armpit can be alarming. For women, it's easy to jump to conclusions, but understanding the potential causes can ease your mind. While breast cancer is a concern, it's often not the immediate reason. More commonly, it's related to muscle strain from exercise or sleeping awkwardly. You might also be experiencing swollen lymph nodes, often a sign that your body is fighting off an infection, like a cold or the flu.
Other possibilities include a skin condition, like a boil or an ingrown hair, especially if you shave. In rarer cases, the pain could stem from nerve irritation or even angina, a heart-related condition. It's crucial to pay attention to any accompanying symptoms: fever, rash, a lump, or pain radiating down your arm. If the pain is severe, persistent, or accompanied by other concerning symptoms, consult your doctor immediately. They can properly diagnose the cause and recommend the appropriate treatment. Don't hesitate to seek medical advice; your health is worth it!
