Swelling underarm
Hello doctor I am 39 years old. I suddenly got up from bed and in the evening I felt something like a swelling in my armpit. Then I checked and it was swelling and not pain. Why did this happen? Last night I had a 13 hour tour during which this hand was stretched for 2-4 hours.

**Response:**
**Answer:**
The **sudden, painless swelling** in your armpit could be due to several causes, but given your recent long journey with arm stretching, the most likely explanations are:
1. **Lymph Node Swelling (Reactive Lymphadenopathy)** – Possibly due to minor infection or irritation.
2. **Muscle Strain or Cyst** – From prolonged arm positioning during travel.
3. **Blocked Sweat Gland (Hidradenitis)** – If the swelling is tender or red.
4. **Lipoma (Fatty Lump)** – Soft, movable, and benign.
### **Next Steps:**
✔ **Self-Check:**
- Monitor for **pain, redness, or fever** (signs of infection).
- Check if the lump is **firm, movable, or growing**.
✔ **When to Worry?**
- If swelling **persists beyond 1-2 weeks** or grows larger.
- If you develop **fever, night sweats, or weight loss**.
### **Recommended Action:**
- Apply a **warm compress** 2-3 times daily.
- Avoid **tight clothing or excessive pressure** on the area.
- If no improvement in **3-5 days**, consult a doctor for **ultrasound or blood tests**.
### **Consultation:**
For a **proper diagnosis and imaging if needed**, contact me on **WhatsApp at eight zero zero nine eight two one three three two**. Most cases are harmless, but evaluation ensures peace of mind.
