[40F] Experiencing severe lower left back pain with difficulty breathing

What might be happening

Based on the information you've provided, the following conditions could be causing your symptoms:

• Musculoskeletal pain: This is a common cause of back pain. It can be due to muscle strain, sprains, or other injuries. It can also be due to chronic conditions like arthritis. The pain is usually localized to the area of damage but can radiate to other areas. It can be exacerbated by physical activity and relieved by rest.

• Pneumonia or Pleurisy: Given your recent history of pneumonia and sepsis, it's possible that your current symptoms are a continuation or recurrence of these conditions. Pneumonia can cause chest pain that radiates to the back, difficulty breathing, and fever. Pleurisy, inflammation of the lining of the lungs, can also cause similar symptoms and can occur after an episode of pneumonia.

• Kidney Infection or Stones: These conditions can cause severe pain in the lower back, side, or abdomen, fever, and other symptoms. The pain can be severe and can radiate to different areas.

• Heart conditions: Given your history of an enlarged heart, it's important to consider conditions like heart disease or heart failure. These can cause a variety of symptoms including back pain and difficulty breathing.

What you can do

Given the severity of your symptoms and your recent medical history, it's important that you seek medical attention as soon as possible.

In the meantime, try to rest and stay hydrated. Over-the-counter pain relievers may help alleviate your pain, but it's important to check with a healthcare provider before starting any new medication.

What you should look out for

You should seek immediate medical attention if you experience any of the following:

• Severe chest pain
• Difficulty breathing
• Confusion or difficulty staying awake
• Blood in your urine
• Fever that's not improving or is getting worse
