i can't stop sneezing.my stomach hurts, sometimes i feel diz

可以,但会有差别：
faint 当形容词时作表语时,（指人）易失去知觉,快要晕倒；dizzy,当形容词讲时,（指人)头晕的,眩晕的,失去平衡的.在这个意义上讲,Faint会略比dizzy程度更严重一些.【经查牛津得出的结果】
为了区别一楼,表达更准备,我直接给出两个词在牛津中的词条解释和权威例句：
Faint：
(a) (of physical abilities) lacking strength （指体力）无力的,虚弱的:in a faint voice 以有气无力的声音 * His breathing became faint.他的呼吸变得微弱了.（b）[pred 作表语] (of people) likely to lose consciousness; giddy （指人）易失去知觉; 昏眩:
She looks/feels faint.她看来[感到]快要晕倒了.(c) [pred 作表语] (of people) weak; exhausted （指人）无力,精疲力竭:The explorers were faint from hunger and cold.探险者们因饥寒交迫而委顿不堪.
Dizzy:
(of a person) feeling as if everything is spinning around; unable to balance; confused （指人）头晕的,眩晕的,失去平衡的,昏乱的:After another glass of whisky I began to feel dizzy.我又喝了一杯威士忌酒之後,就觉得头晕目眩.
还可以再问哈.
