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!
