Hi! I'm 22 year old female, 164 cm tall and weighing 59 kg. I've been having left side chest pain for last few years, recently it has gotten worse with tight, squeezing pain in the chest with palpitation. So, doctor gave me some tests to confirm if it had anything to do with the heart. The ECG report is suspecting anemia and hypothyroid heart disease. But the CBC test is showing that the amount of hemoglobin in my body is just fine but my ESR level has increased considerably. The ECG report also included sinus tachycardia. Should I be worried, do I really have hypothyroidism??
