Tightness and pain in the left upper back?


Hello Doctor, for the past month or so, I have been experiencing discomfort under my left shoulder blade.
There is a persistent tightness, and sometimes I also feel soreness.
I have researched a lot and found that issues with internal organs can cause back discomfort.
I have already seen a gastroenterologist, but I have to wait a month for an abdominal ultrasound.
I am quite worried during this waiting period.
Could you please advise me on how to differentiate whether the discomfort is due to internal organ issues or muscle problems? Thank you, Doctor.

How to distinguish between visceral pain and muscle soreness? Visceral pain may be accompanied by related symptoms such as abdominal pain and vomiting.
Muscle pain, on the other hand, is often more localized and can sometimes be related to posture.
There are now musculoskeletal ultrasound techniques available to check for inflammation or abnormalities in the muscles.
Wishing you good health!

When it comes to understanding left back pain, particularly in the area beneath the shoulder blade, it is essential to differentiate between muscular issues and potential organ-related problems. Your symptoms, including a persistent tightness and occasional soreness, can arise from various causes, and it's wise to consider both muscular and visceral origins.

Muscular pain in the back, especially around the shoulder blade area, is often due to muscle strain, overuse, or poor posture. Activities such as lifting heavy objects, repetitive motions, or even prolonged sitting can lead to muscle fatigue and discomfort. In your case, if you have engaged in activities that involve lifting or straining your upper body, this could be a contributing factor. Muscle pain is typically localized, meaning it will feel tender when you press on the affected area, and may improve with rest, stretching, or heat application.

On the other hand, visceral pain, which originates from internal organs, can sometimes manifest as back pain. The organs in the upper abdomen, such as the liver, gallbladder, and stomach, can refer pain to the back. For instance, gallbladder issues may cause pain that radiates to the right shoulder blade, while problems with the spleen or stomach can lead to discomfort on the left side. Visceral pain is often more diffuse and may be accompanied by other symptoms such as nausea, changes in appetite, or digestive issues.

To help distinguish between these two types of pain, consider the following:
1. Location and Quality of Pain: Muscular pain is usually sharp or aching and is localized to a specific area. In contrast, visceral pain may feel more like a deep, dull ache and can be harder to pinpoint.

2. Associated Symptoms: Pay attention to any additional symptoms. If you experience gastrointestinal symptoms like bloating, changes in bowel habits, or unexplained weight loss, it may indicate an organ-related issue. Conversely, if the pain worsens with certain movements or positions, it is more likely muscular.

3. Response to Treatment: If you try muscle-relaxing techniques, such as stretching, heat application, or over-the-counter pain relievers, and notice improvement, it suggests a muscular origin. If the pain persists despite these interventions, further investigation may be warranted.

4. Timing and Triggers: Note when the pain occurs. If it arises after specific activities or positions, it leans towards a muscular cause. If it occurs randomly or is associated with meals, it may be related to an organ.

Given that you have already consulted a gastroenterologist and are awaiting an abdominal ultrasound, it is prudent to continue monitoring your symptoms. If your pain worsens, or if you develop new symptoms such as fever, significant weight loss, or persistent digestive issues, seek medical attention sooner rather than later.

In the meantime, consider gentle stretching exercises, maintaining good posture, and avoiding activities that exacerbate the pain. If you suspect that your pain is muscular, physical therapy may also be beneficial in strengthening the surrounding muscles and improving flexibility.

Ultimately, while waiting for your ultrasound results, it is essential to remain vigilant about your symptoms and communicate any changes to your healthcare provider. They can provide further guidance and determine if additional diagnostic tests or referrals to specialists are necessary. Your health and peace of mind are paramount, so do not hesitate to seek help if your concerns persist.
