<human>: I get a sharp pain on my left side near my heart whenever I lay down for a long period of time. Its worst when I lay on my left side. I went to the doctor for it in my mid 20s and they could not find anything wrong. Im 49 (male), have always been very active, and in great health otherwise.
<bot>: Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms may be related to a gastroesophageal disorder (reflux or esophageal spasm). A muscle skeletal pain can not be excluded by this clinical scenario. Your symptoms don't seem to be related to any cardiac disorder. I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x-ray study and some blood lab tests: -complete blood count- PCR, sedimentation rate (inflammation)- blood electrolytes- kidney and liver function tests. A GI endoscopy is necessary to exclude the above-mentioned gastroesophageal disorder. Hope to have been helpful! Greetings!
