Understanding subtle body tremors can be quite complex, especially when they arise after a significant health event such as food poisoning. Based on your description, it seems that you are experiencing a combination of physical and psychological symptoms that may be interconnected.
Firstly, the tremors you are feeling could be attributed to several factors, including anxiety, electrolyte imbalances, and the aftermath of your gastrointestinal distress. After experiencing food poisoning, it is common for the body to go through a period of recovery, during which symptoms like increased heart rate, weakness, and gastrointestinal discomfort can persist.
1. Anxiety and Panic Responses: Your mention of feeling uncomfortable and having a rapid heartbeat when anxious suggests that you may be experiencing anxiety or panic attacks. This is not uncommon after a distressing event like food poisoning, as the body can remain in a heightened state of alertness. The sympathetic nervous system, responsible for the fight-or-flight response, can become overactive, leading to symptoms such as tremors, increased heart rate, and gastrointestinal issues. It’s essential to address these feelings, possibly through cognitive-behavioral therapy (CBT) or mindfulness techniques, which can help manage anxiety and reduce the physical symptoms associated with it.

2. Electrolyte Imbalance: You mentioned having slight deficiencies in sodium and potassium. Electrolytes are crucial for muscle function and nerve signaling. An imbalance can lead to symptoms such as muscle cramps, weakness, and tremors. Given that you have experienced gastrointestinal distress, it is possible that you lost electrolytes through diarrhea and did not adequately replenish them. To improve this, consider incorporating foods rich in these electrolytes, such as bananas (for potassium) and salty snacks (for sodium). In some cases, electrolyte solutions or sports drinks can also help restore balance.

3. Dietary Changes: Your recent dietary adjustments, including eating lighter meals, may also contribute to your symptoms. If your body is not receiving enough nutrients, it can lead to feelings of weakness and exacerbate tremors. Ensure you are consuming a balanced diet that includes adequate proteins, carbohydrates, and fats, along with vitamins and minerals. If you are unsure about your dietary intake, consulting with a nutritionist may provide personalized guidance.

4. Sleep Position and Quality: You noted that changing your sleeping position has affected the tremors. Sleep quality and posture can significantly impact how your body feels. If you are not getting restorative sleep, it can lead to increased stress on the body, contributing to tremors and anxiety. Aim for a comfortable sleeping position that supports your spine and allows for deep, restful sleep.

5. Medical Follow-Up: Since you have already consulted with a cardiologist and a psychiatrist, it would be wise to continue monitoring your symptoms. If the tremors persist or worsen, consider seeking further evaluation from a neurologist to rule out any underlying neurological conditions. Additionally, regular follow-ups with your primary care physician can help manage your overall health and address any ongoing concerns.

In summary, the subtle body tremors you are experiencing could be a multifaceted issue involving anxiety, electrolyte imbalances, dietary changes, and sleep quality. Addressing these areas through a combination of dietary adjustments, anxiety management techniques, and medical follow-up will likely provide the best path toward improvement. Remember to listen to your body and seek help when needed, as recovery is a process that requires time and care.
