<s>[INST] For the past couple of weeks Ive been feeling a fluttering / twitching feeling under or by my right rib cage. I have a fatty liver and didnt know if this is a sign that something may be worsening?  Ive read it could be detoxing too.  It doesnt hurt, but is more annoying (like an eye twitch).  Im overweight and cant reach under my rib cage like some suggest. Should I go to the doctor? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should first rule out arrhythmia (rhythm disturbances in heart) because this can cause Fluttering and twitching sensations in rib cage. So consult doctor and get done 1. ECG 2. 2d echo 3. Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about heart diseases. Sometimes, stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. And lose some weight. This will cause subjective wellbeing and treat your fatty liver too. Don't worry, you will be alright. But first rule out arrhythmia. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
