I have migraine problems since school days. But wearing helmet was not a problem but from some months, when I travel in bike as pillion i get head pressure wearing it, feeling out of breath and really uneasy which causes me panic. But recently i realised these symptoms even if i just wear helmet at home. It happens even with half helmet. And also when going on bike, i feel like my eyes goes dizzy, causing me Anxiety. What could be issue and how to fix it
