Multiomics After Headache Provocation of People Who Are Unable to Have Headache

The investigators will measure multiomic changes (transcriptomics and metabolomics) after headache provocation with isosorbide mononitrate. 3 blood samples, two for RNA and one for metabolomics are taken right before administration of isosorbide mononitrate, 3 hours after administration of isosorbide mononitrate and again 5 hours after administration of isosorbide mononitrate.
