At present you are worried and restless about the headaches
and its interference with your sleep. Perhaps your anxieties are worsening your problems. Try to have a comfortable sleep. Change your mattress and make sure your room is airy.
In the mean time consult an ENT specialist
. Your complain about, 'wooshing and cricket sounds' can be because of tinnitus
which you are experiencing in your ears. Once your ears get treated you will get relieved of much of your problems.
Do not get confused or scared just relax. I don't think you will have but if you have the same problems after your ears are inspected and treated do consult your cardiologist.
