It's understandable to feel concerned about a sudden lump, especially when it’s painful and tender. The good news is that many lumps on the arm, particularly if they are recent and arise from insect bites, are often benign or related to minor issues like irritation or infection. Here's what you should know and do next:

Main Points:

1. The lump could be due to an insect bite or irritation, which is common and generally not serious.
2. Monitor the symptoms closely to assess any changes or worsening.

Explanation:

Insect bites can cause local swelling and tenderness as part of the body’s immune response. The bump could also be a small cyst, a swollen lymph node, or a localized infection. Since you mentioned tenderness and pain, it’s good to observe how it develops over the next few days.

Prioritized Next Steps:

1. Monitor Symptoms: Keep an eye on the lump for changes in size, redness, warmth, or increased pain. Take note if it starts to spread or becomes distinctly worse.

2. Self-Care:

   • Apply a cool compress to reduce swelling and alleviate pain.
   • Over-the-counter pain relief (like ibuprofen or acetaminophen) can help relieve discomfort.
   • Keep the area clean to prevent infection; avoid scratching.

3. Seek Attention if Needed: If you experience:

   • Increasing redness and swelling spreading from the lump.
   • Fever or chills.
   • Severe pain or the lump continues to grow.
   • Pus or drainage from the area.

These symptoms may suggest a more serious condition that requires medical evaluation.

By taking these steps, you'll be able to manage the situation effectively. If you have any specific concerns or notice alarming changes, it’s best to seek further advice. Remember to take care of yourself and reach out if you need more guidance.
