I had high TSH for a few months with low Vit D and B12 and symptoms of weakness and some cardiovascular symptoms such as chest pain after walking or doing some physical activity and bathing. Recently tested again and my MVP and PDW is high with TSH 7.5 and having cardio symptoms like headache and chest pain and heaviness after doing physical activity. What should I do? Please suggest..i also did ECG but it seemed to be normal.
