Re: neck related dizziness
You can have a combination of cervical vertigo from a stiff neck which is sending the wrong message to your brain re: position in space.....this can lead to holding your neck and shoulders even tighter to right yourself....and this in turn leads to stress and anxiety which can lead to Panic Syndrome and you become housebound.
You must try to learn relaxation techniques and fight this. My mother was housebound for most of my childhood.
I have cervical vertigo from a head-on with a drunk driver and work on fighting the neck stiffness. It is a constant battle....good luck !
