I had been experiencing chest pain and discomfort for two months. The family doctor ordered a blood test and a chest X-ray, which showed nothing. According to the doctor, the resting ECG showed slight hypoxia. She recommended the drug agen half a tablet due to low blood pressure. Unfortunately, after a week I had to give up taking the drug because I felt bad after it. The pharmacist at the pharmacy recommended Cardiol C and Alfaridine drops. He feels better. Is it possible that the drops helped, although I have only been taking them for a few days? Could the pain have been stressful and disappear on its own? I still have an appointment with a cardiologist to check if the hypoxia is not due to coronary artery disease. And I'm waiting for the result of 2 X-rays of the thoracic spine. Sometimes I still feel a slight pressure, but more like a clog in my throat. Could the hypoxia that came out of the ECG go away on its own, or was there something else as an effect? I don't smoke cigarettes and I don't drink alcohol. Can I still have coronary artery disease?
