Understanding the sensations you are experiencing in your left upper abdomen, particularly the vibrations that feel similar to a heartbeat, can be quite perplexing. Given that you've already consulted a cardiologist and received a clean bill of health regarding your heart, we can explore other potential causes for these symptoms.

Firstly, the sensation of vibrations or pulsations in the abdomen can sometimes be attributed to gastrointestinal issues. Conditions such as irritable bowel syndrome (IBS) can lead to abnormal contractions of the intestines, which might be perceived as vibrations or spasms. IBS is often associated with symptoms like abdominal pain, bloating, and changes in bowel habits, which aligns with your experience of pain before bowel movements that resolves afterward.

Another possibility is that the vibrations could be related to the movement of gas within the intestines. If you have a sensitive gastrointestinal tract, the presence of gas can lead to heightened sensations, including vibrations. This can be exacerbated by dietary choices, stress, and other lifestyle factors. Keeping a food diary to track what you eat and any subsequent symptoms may help identify potential triggers.

Additionally, the autonomic nervous system plays a significant role in regulating gut function. If a physician has suggested that you might be experiencing autonomic dysregulation, it could mean that your body's stress response is affecting your gastrointestinal motility. Stress and anxiety can lead to increased muscle tension and altered gut function, which may contribute to the sensations you are feeling.

It's also worth considering the possibility of referred pain or sensations from nearby structures. For example, issues with the spleen, pancreas, or even the diaphragm can sometimes manifest as abdominal discomfort or unusual sensations. Given that you mentioned the pain is more pronounced when sitting or lying down, it might be worthwhile to explore postural factors or muscular issues that could be contributing to your symptoms.

In terms of management, here are some strategies that may help alleviate your symptoms:
1. Dietary Modifications: Consider adopting a low-FODMAP diet, which can help reduce symptoms of IBS by minimizing fermentable carbohydrates that can lead to gas and bloating. Focus on whole foods, and avoid processed foods that may exacerbate your symptoms.

2. Stress Management: Incorporate stress-reduction techniques such as mindfulness, yoga, or deep-breathing exercises. These practices can help regulate the autonomic nervous system and may alleviate gastrointestinal symptoms.

3. Regular Exercise: Engaging in regular physical activity can promote healthy digestion and reduce stress levels. Aim for a balanced routine that includes both aerobic and strength-training exercises.

4. Consultation with a Gastroenterologist: If your symptoms persist, it may be beneficial to seek a second opinion from a gastroenterologist who specializes in functional gastrointestinal disorders. They may recommend further testing, such as an abdominal ultrasound or endoscopy, to rule out any underlying conditions.

5. Medication: If IBS is confirmed, your doctor may prescribe medications to help manage symptoms, such as antispasmodics or medications that target specific symptoms like diarrhea or constipation.

In conclusion, while the sensations you are experiencing can be distressing, they are often manageable with appropriate lifestyle changes and medical guidance. It is essential to continue working closely with your healthcare providers to explore all potential causes and develop a tailored treatment plan that addresses your specific symptoms.
