请问下面的英语有错误吗？

examine只能是动词，此处应该用examination， 或exam。其他ok

没有唉。
如果从更好的角度说 改成 think you'd better have a further examine.before the result comes out更好、

I think you'd better have a further examination ,try to relax yourself before the result comes out and take the medicine before you sleep.It will help you to kill the pain and make you sleep well.
改好了

examine-examination examine不是动词吗~
take the medicine - take your medicine 好些
