I visited a cardiologist recently and was diagnosed with high blood pressure. As I was still having health issues like headache,palpitation,dizziness, muscle pain, i had a complete blood test done and was diagnosed with low haemoglobin/iron, high cholesterol,very low hydroxyvitamin D (3.0). I am still feeling weak and dizzy and getting occasional headaches. Which doctor should I consult and what do I need to be cautious about? (Cardiologist/general physician?)
