Hello dear, thanks for posting your query here.
There could be many reasons for the headache but in your case, most likely it could be drug induced that is due to nitrates.
Nitrates very commonly cause headache but it usually goes away after 2 to 3 weeks if person continues to take it by tachyphylaxis. But if you stop taking nitrates and then after few days again start taking it, you again will have headache.
So continue taking your dose of nitrates.
But I would advise you to see your doctor if that doesn't get relieved after another a week or 2.
I hope this helps you.
Thanks and all the best.
