When it comes to arm pain and swelling, particularly in the upper arm, it is essential to understand the potential causes and when to seek medical help. Based on your description, you have a lump about the size of a nickel on your upper arm that is painful to the touch and feels hard, along with discomfort in your wrist. These symptoms can arise from various conditions, and understanding them can help you determine the appropriate course of action.


Possible Causes of Arm Pain and Swelling
1. Soft Tissue Injury: The lump could be a result of a contusion or hematoma, which occurs when blood vessels are damaged, leading to localized swelling and pain. This is common after trauma or overuse.

2. Bursitis: Inflammation of the bursa, a small fluid-filled sac that reduces friction between tissues, can cause swelling and pain in the arm. This often occurs due to repetitive motion or prolonged pressure on the joint.

3. Tendonitis: Inflammation of the tendons in the shoulder or elbow can lead to pain and swelling in the arm. This is often seen in individuals who engage in repetitive overhead activities.

4. Cysts or Tumors: A hard lump could also indicate a cyst, such as a ganglion cyst, or in rare cases, a benign or malignant tumor. These can cause localized swelling and discomfort.

5. Infection: An infection in the skin or deeper tissues (such as cellulitis) can lead to swelling, redness, and pain. This is often accompanied by systemic symptoms like fever.

6. Lymphadenopathy: Swelling of lymph nodes due to infection or other systemic conditions can also present as a lump in the arm.

7. Nerve Issues: Conditions such as carpal tunnel syndrome or thoracic outlet syndrome can cause wrist pain and discomfort that may radiate up the arm.


When to Seek Medical Help
It is crucial to seek medical attention if you experience any of the following:
- Persistent Pain: If the pain does not improve with rest or over-the-counter pain relief.

- Increasing Swelling: If the swelling worsens or spreads.

- Fever or Chills: These could indicate an infection.

- Numbness or Weakness: If you experience tingling, numbness, or weakness in the arm or hand.

- Changes in Skin Color: Redness or warmth around the lump could suggest inflammation or infection.

- Difficulty Moving the Arm: If you have reduced range of motion or significant discomfort when trying to use the arm.


Recommended Actions
1. Rest and Ice: Initially, resting the arm and applying ice can help reduce swelling and pain.

2. Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help alleviate pain and inflammation.

3. Monitor Symptoms: Keep track of any changes in the lump or associated symptoms.

4. Consult a Healthcare Provider: If symptoms persist or worsen, it is advisable to consult a healthcare provider. They may perform a physical examination and possibly imaging studies (like an ultrasound or MRI) to determine the underlying cause.


Conclusion
In summary, while some causes of arm pain and swelling may resolve on their own, others may require medical intervention. Given the symptoms you described, it is prudent to seek medical advice, especially if the lump persists or if you experience additional symptoms. Early diagnosis and treatment can significantly improve outcomes and prevent complications.
