[34F] Experiencing lumps under arms with tingling and weakness in right arm

What might be happening

Based on the information you've provided, possible diagnoses include:

• Lymphadenopathy: This is a condition where lymph nodes become enlarged or swollen, and it can be a sign of an infection, an immune disorder, or cancer. The lumps under your arms could be swollen lymph nodes. The tingling sensation and weakness in your right arm might be due to the pressure these swollen lymph nodes are putting on the nerves in that area.

  • Further testing would involve a physical examination, blood tests, and possibly a biopsy of the lymph node.

• Breast Cancer: Given your family history of breast cancer, it's important to consider this as a possibility. Lumps in the armpit can sometimes be a sign of breast cancer that has spread to the lymph nodes.

  • Further testing would involve a mammogram, ultrasound, and possibly a biopsy.

• Brachial Plexus Injury: This is an injury to the brachial plexus, the network of nerves that sends signals from your spine to your shoulder, arm, and hand. A brachial plexus injury can cause numbness and weakness in your arm.

  • Further testing would involve a neurological examination, and possibly imaging tests like an MRI or CT scan.

What you can do

It's important to consult a healthcare professional about your symptoms. They can provide a formal assessment and order relevant tests if necessary. In the meantime, you can:

1. Keep a symptom diary: Write down when you notice the lumps, tingling, and weakness, and anything that makes these symptoms better or worse. This can help your healthcare provider diagnose your condition.
2. Avoid activities that make your symptoms worse: If certain movements or activities make the tingling and weakness in your arm worse, try to avoid these until you can see a healthcare provider.
3. Stay hydrated and eat a balanced diet: This can help your body function at its best.

What you should look out for

Reasons to seek immediate medical attention:

• If the lumps become significantly larger or more painful
• If the tingling sensation or weakness in your arm worsens or spreads
• If you notice any changes in your breast tissue, such as lumps, skin changes, or nipple discharge
• If you develop a fever, night sweats, or unintentional weight loss
