<s>[INST] Hi. I just ate some hot popcorn then laid down now Im having heat burn and my left arm feel weird. But this isnt my first time feeling this way. I Google heart attack symptoms and it freaked me out so now im even more scared. Can i be having a heart attack, panic attack or just regular heart burns? [/INST] Hello! Thank you for asking on Chat Doctor! Regarding your concern, your symptoms seem to be related to gastroesophageal reflux or gastritis. These disorders could also explain the feeling in your arm (irradiated pain). I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x-ray and a routine blood check up (fasting glucose, complete blood count, kidney and liver function test, blood electrolytes). It is necessary to perform a gastrointestinal endoscopy to rule in/out the above-mentioned disorders (gastroesophageal reflux, hiatal hernia or gastritis). You should discuss with your attending physician on the above issues. Hope to have been helpful! Greetings! </s>
