When I started to use topical minoxidil I noticed something strange. Sometimes during the day, I get chest discomfort, when I take deep breaths I kinda feel pain near my heart, when I wake up I get random heartaches that last couple of seconds, or during the day. I've not experienced this before starting minox. When I stopped it the side effects subsided. Is this possible that topical minoxidil can cause this? I heard that there is no chance it will get to your bloodstream. Should I continue taking it and hope the side effects will disappear?
