Oral minoxidil hypertension after stopping

A year ago i decided to switch to oral 5mg/daily min from topical and i’ve seen no improvement overall so i decided to switch a week ago and i have some chest pain and trouble sleeping. Can oral minoxidil be the cause? I’m also suffering some stress and anxiety so minoxidil could be increasing the symptoms. What should i do? Should i take it again and slowly reduce the dosage?
