电热蚊香液加热器坏了:英语‘腰酸背痛’的‘酸’和‘痛’分别怎么翻译？

呵呵，其实是一个意思，楼主受汉语的影响了，
ache
pain
这两个词都可以表达,
英语中有这类词汇的，酸即痛,痛既酸,反正都是难受，身体某部位不舒服!

His broken leg gave him a lot of pain.
他的断腿使他非常疼痛。
· She suffers greatly from a pain in the back.
她背痛很厉害。
· Bad teeth often cause pain.
坏牙常引起疼痛。
· He has a pain in the head.
他头痛。
· He gave his mother much pain by acting in such a foolish way.
他干这样的蠢事使他的母亲很痛苦。

不及物动词 vi. 疼痛
to give continuous pain
· Which place aches most?
哪个部位最痛？
· My legs ached after the long walk.
我走了那段长路后觉得腿疼。
· I am aching all over.
我全身都痛。

名词 n. （常用于复合字）痛
(often in compounds) a continous, dull pain

· ear ache

· stomach ache
胃痛
· toothache
牙疼
· aggravate the ache

背疼

这个问题问得好。因为英文里几乎是不分“酸”和“痛”的。腰酸背痛就是backache.或back hurts,or have pain in my back.
如果要说不是痛，而是一种说不上来的酸痛，那可以说“my back feels funny."

酸sour
痛ache

sore, ache, pain
