I have a small lump in my armpit thats slightly swollen, and it hurts a bit when I stretch my arm. What could this be, and should I be concerned?
It sounds like you may have a swollen lymph node in your armpit, which can be caused by various reasons such as infection or inflammation. To help reduce the swelling and pain, you can take over-the-counter pain relievers like acetaminophen. Additionally, you can apply a warm compress to the area for 10-15 minutes a few times a day. If the swelling and pain persist or worsen, it's important to consult with a healthcare professional for further evaluation and treatment.
