I am a fifteen year old female. I m not sure whether i am being paranoid or not, but when i breathe in through either my nose or my mouth i feel a sharp pain in my head on the right side. It only feels very painful when i take a full breath in and when i am breathing normally it s just a dull ache. This doesnt happen regularly but when it does, panadol doesnt help and it goes away after a while. should i be worried or is this normal?
