Sore Bump in Armpit Area
Female, 41 years old. No ongoing medications. No previous medical conditions noted. I underwent a complete hysterectomy on May 7, which marks my significant medical history. For the past few days, I've experienced discomfort in my armpit, but there were no visible signs. However, a small bump appeared last night, and it seems to have enlarged slightly by this morning. I made sure to mark it in the photo I took. I opted not to apply deodorant today and chose to wear a loose-fitting shirt. The area feels tender without any pressure, and it becomes quite painful when I touch it. Currently, it doesn't feel warm to the touch. I am trying to remain calm, especially since it is on my left side. Can anyone offer suggestions about what this might be? I am considering a visit to urgent care after work.

You've observed a sore bump in your armpit, which has recently become tender and slightly larger. It's understandable to feel concerned, especially in the context of your recent hysterectomy. Let's break this down to help ease your worries and provide actionable steps.
Main Points
The bump could be due to several possible causes such as a blocked sweat gland, an infection, or a swollen lymph node. The tenderness and size change are important signs to monitor. While it's good that you're remaining calm, you should keep a close eye on this bump.
Explanation
-
Possible Causes:
- Blocked Sweat Gland (Sebaceous cyst): Sometimes, hair follicles or sweat glands can become blocked, leading to a bump.
- Infection: This could be a localized infection, which can cause lumps that are tender and painful.
- Lymph Node Swelling: Lymph nodes in your armpit can swell in response to infections elsewhere in the body.
-
Symptom Monitoring: The absence of warmth and the fact that it’s becoming painful when touched are noteworthy. It's reassuring that you're attentive to these changes.
Next Steps
- Observe the Bump: Monitor any changes in size, shape, or pain level over the next day or two.
- Apply Warm Compress: Gently place a warm, damp cloth on the area for 10-15 minutes a few times daily to soothe discomfort.
- Manage Pain: Consider over-the-counter pain relievers like ibuprofen or acetaminophen if the pain becomes bothersome.
- Avoid Irritants: Since you’ve already opted for no deodorant and loose-fitting clothing, continue this to avoid further irritation.
- Document Changes: Take note of any additional symptoms such as fever, increased redness, or drainage from the bump, as this can help in evaluating it.
If the bump continues to grow, becomes increasingly painful, develops a fever, or shows signs of infection (such as warmth, redness, or pus), definitely consider your visit to urgent care sooner rather than later. In the meantime, try to stay relaxed and take care! If you have more questions or need further guidance, feel free to ask.

Inquiry About Elevated Blood Platelet Levels
Hello everyone, I’m a 32-year-old female, weighing approximately 270 pounds, and I've been facing a series of health challenges lately.
