I was recently diagnosed with stage 1 hypertension, and have been having issues finding a medicine that works for me. The doctor already had to switch me off of Methyldopa, due to an apparent allergy, and put me on Nifedipine ER (30mg once daily) I have been on the drug for almost a week, and every night about 2 hours after I take it, I get head to toe flushing. I turn BRIGHT red. Should I call the doc on this too?? Will this fade in time? It is quite frustrating...

Thank you!!
