<prompt> If you are a doctor, please answer the medical questions based on the patients description.I feel this pulsating feeling just below the left side of my chest closer to my side. Its been going on now for 7days. I am thirsty every night also for years. Very fatigued for a long time also. Have had hemmorhoids for a couplenof years too. My urine smells bad too.  <response>: Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms may be related to a metabolic disorder or a chronic infection. I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x-ray and some lab tests: - complete blood count for chronic anemia- blood fasting glucose-kidney and liver function tests-blood electrolytes- PCR and sedimentation rate-blood and urine osmolarity-cortisol plasma levels for the Chat Doctor. Meanwhile, I would advise to closely monitor your blood pressure for possible hypotension, take plenty of fluids water and juices and avoid straining physical activity. Hope to have been helpful!
