ive been having chest pain for a few months now which i was told was from my back since i need my back cracked every month . i also have to get my neck cracked bc the base of my skull pops out. ive always been told i had hypoglycemia not like terrible though. but idk if like the food im eating is making me feel tired and headaches or the hypoglycemia. but my head it always feels like tired and a lil achey sometimes.. im just worried that something seriuos could be wrong with my head or my heart.. how do i know ?
