[44F] Experiencing right-sided pain and intermittent fevers

What might be happening

Based on the symptoms you've described, there are a few possibilities to consider:

1. Pulmonary Embolism: This is a serious condition where a blood clot blocks one of the arteries in your lungs. Symptoms can include sudden shortness of breath, chest pain that worsens with deep breathing, and a rapid heart rate. Given your family history of blood clots and smoking history, this is a possibility that should be ruled out immediately.

2. Pleurisy or Pleural Effusion: This involves inflammation of the tissues lining your lungs and chest cavity, causing sharp chest pain that worsens with breathing or coughing. Your history of COPD and smoking could contribute to this condition.

3. Costochondritis: This is an inflammation of the cartilage that connects a rib to the breastbone, which can cause chest pain. The swelling and bruising under your breastbone might be related to this condition.

4. Pneumonia: An infection that inflames the air sacs in one or both lungs, which can cause chest pain, fever, and difficulty breathing. Your increased coughing and fever could be indicative of this.

What you can do

1. Seek Immediate Medical Attention: Given the severity of your symptoms, especially the chest pain, shortness of breath, and fever, it's crucial to seek medical attention as soon as possible. These symptoms could indicate a serious condition that requires prompt evaluation and treatment.

2. Call 911 or Go to the Emergency Room: If you experience worsening symptoms, such as increased shortness of breath, severe chest pain, or if you feel light-headed, please call 911 or have someone take you to the emergency room immediately.

3. Avoid Smoking: Smoking can exacerbate your symptoms and contribute to respiratory issues. Consider seeking help to quit smoking, which can improve your overall lung health.

4. Rest and Monitor Symptoms: While waiting for medical evaluation, try to rest and avoid activities that worsen your symptoms. Keep track of any changes in your symptoms to report to your healthcare provider.

Please remember that while I can provide information and suggestions, it's essential to consult with a healthcare professional for a formal diagnosis and appropriate treatment. Your health and safety are the top priority.
