Experiencing side effects (dizziness, nausea, headache, chest pain) possibly from Minoxidil. How long will it last?

I've started using minoxidil 2 months ago, the last 2 weeks I've started facing some serious side effects like dizziness nausea headache chest pain. I've done several test(blood, urine, stool, cardio etc ) and nothing was noticed. after 2 weeks of stopping the minoxidil the aide effects are still there but woth slight improvement. Do you think these side effects are due to minoxidil? And for how long it will last? And any medicine can be taken?
