Is My Chest Pain from Minoxidil?

I had used minoxidil for hair growth 12 months ago for 4 months. I stopped it. That time I have not observed any side effects. Now I am again using the same to control the hair fall. Now I am feeling like chest pain (muscular). Is it because of minoxidil..? how safe this medicine ..? because chest and heart are more important than the hair.. Thanks in advance

Chest pain with minoxidil may indicated coronary artery disease, because minoxidil can drop blood pressure and cause reduced circulation to the coronary arteries (angina). Please see a doctor to make that diagnosis, as taking minoxidil may be the way you find out that you have some serious heart problem.
