Underarm Pain: When to Seek Medical Attention - Family Medicine

Underarm pain, especially when accompanied by other symptoms such as shoulder pain, back pain, and chest discomfort, can be concerning and warrants careful consideration. Given that you have been experiencing this pain intermittently for about a month, it is advisable to seek medical attention. While it may initially seem like a symptom related to your menstrual cycle, the persistence and combination of symptoms suggest that a more thorough evaluation is necessary.

There are several potential causes for underarm pain, and understanding these can help guide your decision to seek medical care. Common causes include:
1. Musculoskeletal Issues: Pain in the underarm area can often be related to muscle strain or injury, particularly if you have engaged in activities that involve lifting or repetitive movements. Conditions such as rotator cuff injuries or shoulder impingement can also cause referred pain to the underarm.

2. Nerve Compression: Conditions like thoracic outlet syndrome, where nerves or blood vessels are compressed in the space between your collarbone and first rib, can lead to pain in the shoulder and underarm area. This can also cause numbness or tingling in the arm.

3. Lymphatic Issues: The underarm area contains lymph nodes, and swelling or inflammation of these nodes can indicate an infection or other medical conditions. Conditions such as lymphadenopathy or even more serious issues like lymphoma should be ruled out.

4. Cardiac Concerns: Chest discomfort, especially when associated with pain radiating to the shoulder or underarm, can sometimes indicate cardiac issues. While this is less common, it is critical to take any chest-related symptoms seriously, particularly if they are accompanied by shortness of breath, sweating, or nausea.

5. Referred Pain: Sometimes, pain in the underarm can be referred from other areas, such as the heart, lungs, or even gastrointestinal tract. This means that the source of the pain may not be in the underarm itself but could be related to another underlying condition.

Given your symptoms of persistent pain, difficulty sleeping, and the sensation of chest tightness, it is essential to consult with a healthcare provider. A primary care physician can perform a thorough evaluation, which may include a physical examination, imaging studies (like X-rays or MRIs), and possibly blood tests to rule out infections or other systemic issues.

In terms of which specialist to see, starting with a primary care physician is a good approach. They can assess your symptoms and refer you to a specialist if necessary, such as an orthopedic surgeon for musculoskeletal issues, a neurologist for nerve-related concerns, or a cardiologist if there are indications of heart-related problems.

In the meantime, while you await your appointment, you might find some relief through conservative measures such as applying heat or ice to the affected area, practicing gentle stretching exercises, and avoiding activities that exacerbate your pain. However, if your symptoms worsen or you experience new symptoms such as severe chest pain, shortness of breath, or fainting, seek emergency medical attention immediately.

In summary, while it may initially seem like a benign issue, the combination of your symptoms and their persistence suggests that a medical evaluation is warranted. Taking proactive steps to address your health concerns is always the best course of action.
